Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178592, here are decompositions:

  • 31 + 178561 = 178592
  • 61 + 178531 = 178592
  • 79 + 178513 = 178592
  • 103 + 178489 = 178592
  • 151 + 178441 = 178592
  • 199 + 178393 = 178592
  • 241 + 178351 = 178592
  • 331 + 178261 = 178592

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 178,592 and was likely granted around 1875.

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

Position in π

The digit sequence 178592 first appears in π at position 904,916 of the decimal expansion (the 904,916ordinal-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.
