Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38628, here are decompositions:

  • 17 + 38611 = 38628
  • 19 + 38609 = 38628
  • 59 + 38569 = 38628
  • 61 + 38567 = 38628
  • 67 + 38561 = 38628
  • 71 + 38557 = 38628
  • 127 + 38501 = 38628
  • 167 + 38461 = 38628

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38628 first appears in π at position 150,107 of the decimal expansion (the 150,107ordinal-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.
