Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158216, here are decompositions:

  • 7 + 158209 = 158216
  • 73 + 158143 = 158216
  • 103 + 158113 = 158216
  • 139 + 158077 = 158216
  • 199 + 158017 = 158216
  • 283 + 157933 = 158216
  • 349 + 157867 = 158216
  • 379 + 157837 = 158216

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 158,216 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 158216 first appears in π at position 107,823 of the decimal expansion (the 107,823ordinal-suffix:rd 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.
