Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28622, here are decompositions:

  • 3 + 28619 = 28622
  • 19 + 28603 = 28622
  • 31 + 28591 = 28622
  • 43 + 28579 = 28622
  • 73 + 28549 = 28622
  • 109 + 28513 = 28622
  • 193 + 28429 = 28622
  • 211 + 28411 = 28622

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28622 first appears in π at position 38,067 of the decimal expansion (the 38,067ordinal-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.
