Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555858, here are decompositions:

  • 5 + 555853 = 555858
  • 29 + 555829 = 555858
  • 31 + 555827 = 555858
  • 97 + 555761 = 555858
  • 151 + 555707 = 555858
  • 167 + 555691 = 555858
  • 181 + 555677 = 555858
  • 197 + 555661 = 555858

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 555,858 and was likely granted around 1895.

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

Position in π

The digit sequence 555858 first appears in π at position 39,925 of the decimal expansion (the 39,925ordinal-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.
