Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548390, here are decompositions:

  • 19 + 548371 = 548390
  • 43 + 548347 = 548390
  • 67 + 548323 = 548390
  • 127 + 548263 = 548390
  • 151 + 548239 = 548390
  • 163 + 548227 = 548390
  • 307 + 548083 = 548390
  • 331 + 548059 = 548390

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 548,390 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 548390 first appears in π at position 549,922 of the decimal expansion (the 549,922ordinal-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.
