Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1454, here are decompositions:
- 3 + 1451 = 1454
- 7 + 1447 = 1454
- 31 + 1423 = 1454
- 73 + 1381 = 1454
- 127 + 1327 = 1454
- 151 + 1303 = 1454
- 157 + 1297 = 1454
- 163 + 1291 = 1454
Showing the first eight; more decompositions exist.

The digit sequence 1454 first appears in π at position 1,812 of the decimal expansion (the 1,812ordinal-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.
