Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1330, here are decompositions:
- 3 + 1327 = 1330
- 11 + 1319 = 1330
- 23 + 1307 = 1330
- 29 + 1301 = 1330
- 41 + 1289 = 1330
- 47 + 1283 = 1330
- 53 + 1277 = 1330
- 71 + 1259 = 1330
Showing the first eight; more decompositions exist.

The digit sequence 1330 first appears in π at position 363 of the decimal expansion (the 363ordinal-suffix:rd 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.
