Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178084, here are decompositions:

  • 17 + 178067 = 178084
  • 47 + 178037 = 178084
  • 83 + 178001 = 178084
  • 131 + 177953 = 178084
  • 167 + 177917 = 178084
  • 191 + 177893 = 178084
  • 197 + 177887 = 178084
  • 293 + 177791 = 178084

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 178,084 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 178084 first appears in π at position 15,510 of the decimal expansion (the 15,510ordinal-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.
