Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40064, here are decompositions:

  • 127 + 39937 = 40064
  • 163 + 39901 = 40064
  • 181 + 39883 = 40064
  • 223 + 39841 = 40064
  • 331 + 39733 = 40064
  • 337 + 39727 = 40064
  • 397 + 39667 = 40064
  • 433 + 39631 = 40064

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40064 first appears in π at position 218,648 of the decimal expansion (the 218,648ordinal-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.
