Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164158, here are decompositions:

  • 11 + 164147 = 164158
  • 41 + 164117 = 164158
  • 101 + 164057 = 164158
  • 107 + 164051 = 164158
  • 167 + 163991 = 164158
  • 179 + 163979 = 164158
  • 257 + 163901 = 164158
  • 311 + 163847 = 164158

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 164,158 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 164158 first appears in π at position 826,122 of the decimal expansion (the 826,122ordinal-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.
