Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28048, here are decompositions:

  • 17 + 28031 = 28048
  • 29 + 28019 = 28048
  • 47 + 28001 = 28048
  • 101 + 27947 = 28048
  • 107 + 27941 = 28048
  • 131 + 27917 = 28048
  • 197 + 27851 = 28048
  • 239 + 27809 = 28048

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28048 first appears in π at position 109,155 of the decimal expansion (the 109,155ordinal-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.
