Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128058, here are decompositions:

  • 5 + 128053 = 128058
  • 11 + 128047 = 128058
  • 37 + 128021 = 128058
  • 61 + 127997 = 128058
  • 79 + 127979 = 128058
  • 107 + 127951 = 128058
  • 127 + 127931 = 128058
  • 137 + 127921 = 128058

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 128,058 and was likely granted around 1872.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 128058 first appears in π at position 590,989 of the decimal expansion (the 590,989ordinal-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.
