Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158826, here are decompositions:

  • 23 + 158803 = 158826
  • 67 + 158759 = 158826
  • 79 + 158747 = 158826
  • 127 + 158699 = 158826
  • 163 + 158663 = 158826
  • 179 + 158647 = 158826
  • 193 + 158633 = 158826
  • 229 + 158597 = 158826

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 158,826 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 158826 first appears in π at position 38,352 of the decimal expansion (the 38,352ordinal-suffix:nd 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.
