Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27906, here are decompositions:

  • 5 + 27901 = 27906
  • 13 + 27893 = 27906
  • 23 + 27883 = 27906
  • 59 + 27847 = 27906
  • 79 + 27827 = 27906
  • 83 + 27823 = 27906
  • 89 + 27817 = 27906
  • 97 + 27809 = 27906

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27906 first appears in π at position 9,252 of the decimal expansion (the 9,252ordinal-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.
