Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2766, here are decompositions:
- 13 + 2753 = 2766
- 17 + 2749 = 2766
- 37 + 2729 = 2766
- 47 + 2719 = 2766
- 53 + 2713 = 2766
- 59 + 2707 = 2766
- 67 + 2699 = 2766
- 73 + 2693 = 2766
Showing the first eight; more decompositions exist.

The digit sequence 2766 first appears in π at position 8,940 of the decimal expansion (the 8,940ordinal-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.
