Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1296, here are decompositions:
- 5 + 1291 = 1296
- 7 + 1289 = 1296
- 13 + 1283 = 1296
- 17 + 1279 = 1296
- 19 + 1277 = 1296
- 37 + 1259 = 1296
- 47 + 1249 = 1296
- 59 + 1237 = 1296
Showing the first eight; more decompositions exist.

The digit sequence 1296 first appears in π at position 2,341 of the decimal expansion (the 2,341ordinal-suffix:st 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.
