Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61568, here are decompositions:
- 7 + 61561 = 61568
- 61 + 61507 = 61568
- 97 + 61471 = 61568
- 127 + 61441 = 61568
- 151 + 61417 = 61568
- 211 + 61357 = 61568
- 229 + 61339 = 61568
- 271 + 61297 = 61568
Showing the first eight; more decompositions exist.

The digit sequence 61568 first appears in π at position 184,838 of the decimal expansion (the 184,838ordinal-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.
