Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25164, here are decompositions:
- 11 + 25153 = 25164
- 17 + 25147 = 25164
- 37 + 25127 = 25164
- 43 + 25121 = 25164
- 47 + 25117 = 25164
- 53 + 25111 = 25164
- 67 + 25097 = 25164
- 107 + 25057 = 25164
Showing the first eight; more decompositions exist.

The digit sequence 25164 first appears in π at position 106,647 of the decimal expansion (the 106,647ordinal-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.
