Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163258, here are decompositions:

  • 47 + 163211 = 163258
  • 59 + 163199 = 163258
  • 89 + 163169 = 163258
  • 107 + 163151 = 163258
  • 131 + 163127 = 163258
  • 149 + 163109 = 163258
  • 197 + 163061 = 163258
  • 239 + 163019 = 163258

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 163,258 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 163258 first appears in π at position 710,985 of the decimal expansion (the 710,985ordinal-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.
