Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548638, here are decompositions:

  • 47 + 548591 = 548638
  • 59 + 548579 = 548638
  • 71 + 548567 = 548638
  • 137 + 548501 = 548638
  • 149 + 548489 = 548638
  • 179 + 548459 = 548638
  • 197 + 548441 = 548638
  • 239 + 548399 = 548638

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 548,638 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 548638 first appears in π at position 66,742 of the decimal expansion (the 66,742ordinal-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.
