Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1480, here are decompositions:
- 29 + 1451 = 1480
- 41 + 1439 = 1480
- 47 + 1433 = 1480
- 53 + 1427 = 1480
- 71 + 1409 = 1480
- 107 + 1373 = 1480
- 113 + 1367 = 1480
- 173 + 1307 = 1480
Showing the first eight; more decompositions exist.

The digit sequence 1480 first appears in π at position 103 of the decimal expansion (the 103ordinal-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.
