Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2944, here are decompositions:
- 5 + 2939 = 2944
- 17 + 2927 = 2944
- 41 + 2903 = 2944
- 47 + 2897 = 2944
- 83 + 2861 = 2944
- 101 + 2843 = 2944
- 107 + 2837 = 2944
- 167 + 2777 = 2944
Showing the first eight; more decompositions exist.

The digit sequence 2944 first appears in π at position 15,586 of the decimal expansion (the 15,586ordinal-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.
