Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142328, here are decompositions:

  • 31 + 142297 = 142328
  • 97 + 142231 = 142328
  • 139 + 142189 = 142328
  • 229 + 142099 = 142328
  • 271 + 142057 = 142328
  • 337 + 141991 = 142328
  • 367 + 141961 = 142328
  • 397 + 141931 = 142328

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 142,328 and was likely granted around 1872.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 142328 first appears in π at position 120,150 of the decimal expansion (the 120,150ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
