Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2724, here are decompositions:
- 5 + 2719 = 2724
- 11 + 2713 = 2724
- 13 + 2711 = 2724
- 17 + 2707 = 2724
- 31 + 2693 = 2724
- 37 + 2687 = 2724
- 41 + 2683 = 2724
- 47 + 2677 = 2724
Showing the first eight; more decompositions exist.

The digit sequence 2724 first appears in π at position 477 of the decimal expansion (the 477ordinal-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.
