Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10986, here are decompositions:

  • 7 + 10979 = 10986
  • 13 + 10973 = 10986
  • 29 + 10957 = 10986
  • 37 + 10949 = 10986
  • 47 + 10939 = 10986
  • 83 + 10903 = 10986
  • 97 + 10889 = 10986
  • 103 + 10883 = 10986

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10986 first appears in π at position 48,803 of the decimal expansion (the 48,803ordinal-suffix:rd 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.
