Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169604, here are decompositions:

  • 13 + 169591 = 169604
  • 37 + 169567 = 169604
  • 73 + 169531 = 169604
  • 103 + 169501 = 169604
  • 277 + 169327 = 169604
  • 283 + 169321 = 169604
  • 541 + 169063 = 169604
  • 601 + 169003 = 169604

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 169,604 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 169604 first appears in π at position 424,613 of the decimal expansion (the 424,613ordinal-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.
