Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69664, here are decompositions:
- 3 + 69661 = 69664
- 11 + 69653 = 69664
- 41 + 69623 = 69664
- 71 + 69593 = 69664
- 107 + 69557 = 69664
- 167 + 69497 = 69664
- 173 + 69491 = 69664
- 191 + 69473 = 69664
Showing the first eight; more decompositions exist.

The digit sequence 69664 first appears in π at position 165,907 of the decimal expansion (the 165,907ordinal-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.
