Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28798, here are decompositions:

  • 5 + 28793 = 28798
  • 47 + 28751 = 28798
  • 101 + 28697 = 28798
  • 137 + 28661 = 28798
  • 149 + 28649 = 28798
  • 167 + 28631 = 28798
  • 179 + 28619 = 28798
  • 191 + 28607 = 28798

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28798 first appears in π at position 24,382 of the decimal expansion (the 24,382ordinal-suffix:nd 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.
