Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2988, here are decompositions:
- 17 + 2971 = 2988
- 19 + 2969 = 2988
- 31 + 2957 = 2988
- 61 + 2927 = 2988
- 71 + 2917 = 2988
- 79 + 2909 = 2988
- 101 + 2887 = 2988
- 109 + 2879 = 2988
Showing the first eight; more decompositions exist.

The digit sequence 2988 first appears in π at position 6,937 of the decimal expansion (the 6,937ordinal-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.
