Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7422, here are decompositions:
- 5 + 7417 = 7422
- 11 + 7411 = 7422
- 29 + 7393 = 7422
- 53 + 7369 = 7422
- 71 + 7351 = 7422
- 73 + 7349 = 7422
- 89 + 7333 = 7422
- 101 + 7321 = 7422
Showing the first eight; more decompositions exist.

The digit sequence 7422 first appears in π at position 7,282 of the decimal expansion (the 7,282ordinal-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.
