Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7242, here are decompositions:
- 5 + 7237 = 7242
- 13 + 7229 = 7242
- 23 + 7219 = 7242
- 29 + 7213 = 7242
- 31 + 7211 = 7242
- 83 + 7159 = 7242
- 113 + 7129 = 7242
- 139 + 7103 = 7242
Showing the first eight; more decompositions exist.

The digit sequence 7242 first appears in π at position 1,107 of the decimal expansion (the 1,107ordinal-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.
