Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 174878, here are decompositions:

  • 19 + 174859 = 174878
  • 79 + 174799 = 174878
  • 157 + 174721 = 174878
  • 199 + 174679 = 174878
  • 229 + 174649 = 174878
  • 241 + 174637 = 174878
  • 307 + 174571 = 174878
  • 397 + 174481 = 174878

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 174,878 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 174878 first appears in π at position 7,948 of the decimal expansion (the 7,948ordinal-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.
