Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40738, here are decompositions:

  • 29 + 40709 = 40738
  • 41 + 40697 = 40738
  • 101 + 40637 = 40738
  • 179 + 40559 = 40738
  • 239 + 40499 = 40738
  • 251 + 40487 = 40738
  • 311 + 40427 = 40738
  • 449 + 40289 = 40738

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40738 first appears in π at position 76,441 of the decimal expansion (the 76,441ordinal-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.
