Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27898, here are decompositions:

  • 5 + 27893 = 27898
  • 47 + 27851 = 27898
  • 71 + 27827 = 27898
  • 89 + 27809 = 27898
  • 107 + 27791 = 27898
  • 131 + 27767 = 27898
  • 149 + 27749 = 27898
  • 197 + 27701 = 27898

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27898 first appears in π at position 135,494 of the decimal expansion (the 135,494ordinal-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.
