Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551248, here are decompositions:

  • 17 + 551231 = 551248
  • 29 + 551219 = 551248
  • 41 + 551207 = 551248
  • 149 + 551099 = 551248
  • 179 + 551069 = 551248
  • 251 + 550997 = 551248
  • 311 + 550937 = 551248
  • 389 + 550859 = 551248

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 551,248 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 551248 first appears in π at position 465,689 of the decimal expansion (the 465,689ordinal-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.
