Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1446, here are decompositions:
- 7 + 1439 = 1446
- 13 + 1433 = 1446
- 17 + 1429 = 1446
- 19 + 1427 = 1446
- 23 + 1423 = 1446
- 37 + 1409 = 1446
- 47 + 1399 = 1446
- 73 + 1373 = 1446
Showing the first eight; more decompositions exist.

The digit sequence 1446 first appears in π at position 9,242 of the decimal expansion (the 9,242ordinal-suffix:nd 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.
