Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540578, here are decompositions:

  • 19 + 540559 = 540578
  • 37 + 540541 = 540578
  • 61 + 540517 = 540578
  • 67 + 540511 = 540578
  • 109 + 540469 = 540578
  • 211 + 540367 = 540578
  • 229 + 540349 = 540578
  • 271 + 540307 = 540578

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 540,578 and was likely granted around 1894.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 540578 first appears in π at position 142,351 of the decimal expansion (the 142,351ordinal-suffix:st 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.
