Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555978, here are decompositions:

  • 11 + 555967 = 555978
  • 37 + 555941 = 555978
  • 47 + 555931 = 555978
  • 107 + 555871 = 555978
  • 149 + 555829 = 555978
  • 151 + 555827 = 555978
  • 211 + 555767 = 555978
  • 239 + 555739 = 555978

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 555,978 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 555978 first appears in π at position 283,221 of the decimal expansion (the 283,221ordinal-suffix:st 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.
