Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142496, here are decompositions:

  • 43 + 142453 = 142496
  • 127 + 142369 = 142496
  • 139 + 142357 = 142496
  • 199 + 142297 = 142496
  • 307 + 142189 = 142496
  • 313 + 142183 = 142496
  • 337 + 142159 = 142496
  • 373 + 142123 = 142496

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 142,496 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 142496 first appears in π at position 370,086 of the decimal expansion (the 370,086ordinal-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.
