Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1464, here are decompositions:
- 5 + 1459 = 1464
- 11 + 1453 = 1464
- 13 + 1451 = 1464
- 17 + 1447 = 1464
- 31 + 1433 = 1464
- 37 + 1427 = 1464
- 41 + 1423 = 1464
- 83 + 1381 = 1464
Showing the first eight; more decompositions exist.

The digit sequence 1464 first appears in π at position 21,988 of the decimal expansion (the 21,988ordinal-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.
