Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40718, here are decompositions:

  • 19 + 40699 = 40718
  • 79 + 40639 = 40718
  • 109 + 40609 = 40718
  • 127 + 40591 = 40718
  • 199 + 40519 = 40718
  • 211 + 40507 = 40718
  • 331 + 40387 = 40718
  • 367 + 40351 = 40718

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40718 first appears in π at position 50,512 of the decimal expansion (the 50,512ordinal-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.
