Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540240, here are decompositions:

  • 7 + 540233 = 540240
  • 23 + 540217 = 540240
  • 37 + 540203 = 540240
  • 53 + 540187 = 540240
  • 59 + 540181 = 540240
  • 61 + 540179 = 540240
  • 67 + 540173 = 540240
  • 73 + 540167 = 540240

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 540,240 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 540240 first appears in π at position 219,613 of the decimal expansion (the 219,613ordinal-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.
