Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177458, here are decompositions:

  • 31 + 177427 = 177458
  • 37 + 177421 = 177458
  • 79 + 177379 = 177458
  • 139 + 177319 = 177458
  • 157 + 177301 = 177458
  • 241 + 177217 = 177458
  • 331 + 177127 = 177458
  • 349 + 177109 = 177458

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 177,458 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 177458 first appears in π at position 110,313 of the decimal expansion (the 110,313ordinal-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.
