Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28450, here are decompositions:

  • 3 + 28447 = 28450
  • 11 + 28439 = 28450
  • 17 + 28433 = 28450
  • 41 + 28409 = 28450
  • 47 + 28403 = 28450
  • 101 + 28349 = 28450
  • 131 + 28319 = 28450
  • 167 + 28283 = 28450

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28450 first appears in π at position 46,521 of the decimal expansion (the 46,521ordinal-suffix:st 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.
