Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550618, here are decompositions:

  • 11 + 550607 = 550618
  • 41 + 550577 = 550618
  • 149 + 550469 = 550618
  • 179 + 550439 = 550618
  • 191 + 550427 = 550618
  • 239 + 550379 = 550618
  • 281 + 550337 = 550618
  • 449 + 550169 = 550618

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 550,618 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 550618 first appears in π at position 271,742 of the decimal expansion (the 271,742ordinal-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.
