Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2966, here are decompositions:
- 3 + 2963 = 2966
- 13 + 2953 = 2966
- 79 + 2887 = 2966
- 109 + 2857 = 2966
- 163 + 2803 = 2966
- 199 + 2767 = 2966
- 277 + 2689 = 2966
- 283 + 2683 = 2966
Showing the first eight; more decompositions exist.

The digit sequence 2966 first appears in π at position 4,433 of the decimal expansion (the 4,433ordinal-suffix:rd 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.
