Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13648, here are decompositions:

  • 29 + 13619 = 13648
  • 71 + 13577 = 13648
  • 149 + 13499 = 13648
  • 179 + 13469 = 13648
  • 191 + 13457 = 13648
  • 197 + 13451 = 13648
  • 227 + 13421 = 13648
  • 251 + 13397 = 13648

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13648 first appears in π at position 168,948 of the decimal expansion (the 168,948ordinal-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.
