Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1246, here are decompositions:
- 17 + 1229 = 1246
- 23 + 1223 = 1246
- 29 + 1217 = 1246
- 53 + 1193 = 1246
- 59 + 1187 = 1246
- 83 + 1163 = 1246
- 137 + 1109 = 1246
- 149 + 1097 = 1246
Showing the first eight; more decompositions exist.

The digit sequence 1246 first appears in π at position 2,287 of the decimal expansion (the 2,287ordinal-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.
