Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163836, here are decompositions:

  • 17 + 163819 = 163836
  • 47 + 163789 = 163836
  • 83 + 163753 = 163836
  • 103 + 163733 = 163836
  • 107 + 163729 = 163836
  • 139 + 163697 = 163836
  • 157 + 163679 = 163836
  • 163 + 163673 = 163836

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 163,836 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 163836 first appears in π at position 141,316 of the decimal expansion (the 141,316ordinal-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.
