Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63998, here are decompositions:

  • 97 + 63901 = 63998
  • 157 + 63841 = 63998
  • 199 + 63799 = 63998
  • 271 + 63727 = 63998
  • 307 + 63691 = 63998
  • 331 + 63667 = 63998
  • 349 + 63649 = 63998
  • 397 + 63601 = 63998

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 63998 first appears in π at position 168,602 of the decimal expansion (the 168,602ordinal-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.
