Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40470, here are decompositions:

  • 11 + 40459 = 40470
  • 37 + 40433 = 40470
  • 41 + 40429 = 40470
  • 43 + 40427 = 40470
  • 47 + 40423 = 40470
  • 83 + 40387 = 40470
  • 109 + 40361 = 40470
  • 113 + 40357 = 40470

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40470 first appears in π at position 28,986 of the decimal expansion (the 28,986ordinal-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.
