Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162430, here are decompositions:

  • 11 + 162419 = 162430
  • 17 + 162413 = 162430
  • 41 + 162389 = 162430
  • 71 + 162359 = 162430
  • 137 + 162293 = 162430
  • 167 + 162263 = 162430
  • 173 + 162257 = 162430
  • 179 + 162251 = 162430

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 162,430 and was likely granted around 1874.

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

Position in π

The digit sequence 162430 first appears in π at position 166,886 of the decimal expansion (the 166,886ordinal-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.
