Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1282, here are decompositions:
- 3 + 1279 = 1282
- 5 + 1277 = 1282
- 23 + 1259 = 1282
- 53 + 1229 = 1282
- 59 + 1223 = 1282
- 89 + 1193 = 1282
- 101 + 1181 = 1282
- 131 + 1151 = 1282
Showing the first eight; more decompositions exist.

The digit sequence 1282 first appears in π at position 3,690 of the decimal expansion (the 3,690ordinal-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.
