Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71804, here are decompositions:

  • 43 + 71761 = 71804
  • 97 + 71707 = 71804
  • 157 + 71647 = 71804
  • 211 + 71593 = 71804
  • 241 + 71563 = 71804
  • 277 + 71527 = 71804
  • 331 + 71473 = 71804
  • 367 + 71437 = 71804

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 71804 first appears in π at position 88,916 of the decimal expansion (the 88,916ordinal-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.
