Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2616, here are decompositions:

  • 7 + 2609 = 2616
  • 23 + 2593 = 2616
  • 37 + 2579 = 2616
  • 59 + 2557 = 2616
  • 67 + 2549 = 2616
  • 73 + 2543 = 2616
  • 113 + 2503 = 2616
  • 139 + 2477 = 2616

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 2616 first appears in π at position 19,504 of the decimal expansion (the 19,504ordinal-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.
