Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158804, here are decompositions:

  • 13 + 158791 = 158804
  • 43 + 158761 = 158804
  • 73 + 158731 = 158804
  • 157 + 158647 = 158804
  • 193 + 158611 = 158804
  • 223 + 158581 = 158804
  • 241 + 158563 = 158804
  • 277 + 158527 = 158804

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 158,804 and was likely granted around 1873.

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

Position in π

The digit sequence 158804 first appears in π at position 360,266 of the decimal expansion (the 360,266ordinal-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.
