Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548442, here are decompositions:

  • 19 + 548423 = 548442
  • 43 + 548399 = 548442
  • 71 + 548371 = 548442
  • 79 + 548363 = 548442
  • 151 + 548291 = 548442
  • 179 + 548263 = 548442
  • 199 + 548243 = 548442
  • 229 + 548213 = 548442

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 548,442 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 548442 first appears in π at position 619,122 of the decimal expansion (the 619,122ordinal-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.
