Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28850, here are decompositions:

  • 7 + 28843 = 28850
  • 13 + 28837 = 28850
  • 37 + 28813 = 28850
  • 43 + 28807 = 28850
  • 61 + 28789 = 28850
  • 79 + 28771 = 28850
  • 97 + 28753 = 28850
  • 127 + 28723 = 28850

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28850 first appears in π at position 21,105 of the decimal expansion (the 21,105ordinal-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.
