Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169240, here are decompositions:

  • 23 + 169217 = 169240
  • 41 + 169199 = 169240
  • 59 + 169181 = 169240
  • 89 + 169151 = 169240
  • 173 + 169067 = 169240
  • 191 + 169049 = 169240
  • 233 + 169007 = 169240
  • 263 + 168977 = 169240

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 169,240 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 169240 first appears in π at position 46,436 of the decimal expansion (the 46,436ordinal-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.
