Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8842, here are decompositions:

  • 3 + 8839 = 8842
  • 5 + 8837 = 8842
  • 11 + 8831 = 8842
  • 23 + 8819 = 8842
  • 59 + 8783 = 8842
  • 89 + 8753 = 8842
  • 101 + 8741 = 8842
  • 149 + 8693 = 8842

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8842 first appears in π at position 13,156 of the decimal expansion (the 13,156ordinal-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.
