Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1512, here are decompositions:
- 13 + 1499 = 1512
- 19 + 1493 = 1512
- 23 + 1489 = 1512
- 29 + 1483 = 1512
- 31 + 1481 = 1512
- 41 + 1471 = 1512
- 53 + 1459 = 1512
- 59 + 1453 = 1512
Showing the first eight; more decompositions exist.

The digit sequence 1512 first appears in π at position 5,220 of the decimal expansion (the 5,220ordinal-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.
