Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28632, here are decompositions:

  • 5 + 28627 = 28632
  • 11 + 28621 = 28632
  • 13 + 28619 = 28632
  • 29 + 28603 = 28632
  • 41 + 28591 = 28632
  • 53 + 28579 = 28632
  • 59 + 28573 = 28632
  • 61 + 28571 = 28632

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28632 first appears in π at position 22,636 of the decimal expansion (the 22,636ordinal-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.
