Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1466, here are decompositions:
- 7 + 1459 = 1466
- 13 + 1453 = 1466
- 19 + 1447 = 1466
- 37 + 1429 = 1466
- 43 + 1423 = 1466
- 67 + 1399 = 1466
- 139 + 1327 = 1466
- 163 + 1303 = 1466
Showing the first eight; more decompositions exist.

The digit sequence 1466 first appears in π at position 3,125 of the decimal expansion (the 3,125ordinal-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.
