Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86920, here are decompositions:

  • 59 + 86861 = 86920
  • 83 + 86837 = 86920
  • 107 + 86813 = 86920
  • 137 + 86783 = 86920
  • 149 + 86771 = 86920
  • 167 + 86753 = 86920
  • 191 + 86729 = 86920
  • 227 + 86693 = 86920

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 86920 first appears in π at position 133,803 of the decimal expansion (the 133,803ordinal-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.
