Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 98820, here are decompositions:

  • 11 + 98809 = 98820
  • 13 + 98807 = 98820
  • 19 + 98801 = 98820
  • 41 + 98779 = 98820
  • 47 + 98773 = 98820
  • 83 + 98737 = 98820
  • 89 + 98731 = 98820
  • 103 + 98717 = 98820

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 98820 first appears in π at position 3,469 of the decimal expansion (the 3,469ordinal-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.
