Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2916, here are decompositions:
- 7 + 2909 = 2916
- 13 + 2903 = 2916
- 19 + 2897 = 2916
- 29 + 2887 = 2916
- 37 + 2879 = 2916
- 59 + 2857 = 2916
- 73 + 2843 = 2916
- 79 + 2837 = 2916
Showing the first eight; more decompositions exist.

The digit sequence 2916 first appears in π at position 3,368 of the decimal expansion (the 3,368ordinal-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.
