Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6988, here are decompositions:
- 5 + 6983 = 6988
- 11 + 6977 = 6988
- 17 + 6971 = 6988
- 29 + 6959 = 6988
- 41 + 6947 = 6988
- 71 + 6917 = 6988
- 89 + 6899 = 6988
- 131 + 6857 = 6988
Showing the first eight; more decompositions exist.

The digit sequence 6988 first appears in π at position 3,468 of the decimal expansion (the 3,468ordinal-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.
