Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184778, here are decompositions:

  • 67 + 184711 = 184778
  • 109 + 184669 = 184778
  • 127 + 184651 = 184778
  • 151 + 184627 = 184778
  • 211 + 184567 = 184778
  • 331 + 184447 = 184778
  • 337 + 184441 = 184778
  • 409 + 184369 = 184778

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 184,778 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 184778 first appears in π at position 159,576 of the decimal expansion (the 159,576ordinal-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.
