Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1492, here are decompositions:
- 3 + 1489 = 1492
- 5 + 1487 = 1492
- 11 + 1481 = 1492
- 41 + 1451 = 1492
- 53 + 1439 = 1492
- 59 + 1433 = 1492
- 83 + 1409 = 1492
- 131 + 1361 = 1492
Showing the first eight; more decompositions exist.

The digit sequence 1492 first appears in π at position 19,915 of the decimal expansion (the 19,915ordinal-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.
