Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29818, here are decompositions:

  • 29 + 29789 = 29818
  • 59 + 29759 = 29818
  • 101 + 29717 = 29818
  • 149 + 29669 = 29818
  • 251 + 29567 = 29818
  • 281 + 29537 = 29818
  • 317 + 29501 = 29818
  • 389 + 29429 = 29818

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 29818 first appears in π at position 18,728 of the decimal expansion (the 18,728ordinal-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.
