Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008, here are decompositions:
- 11 + 997 = 1008
- 17 + 991 = 1008
- 31 + 977 = 1008
- 37 + 971 = 1008
- 41 + 967 = 1008
- 61 + 947 = 1008
- 67 + 941 = 1008
- 71 + 937 = 1008
Showing the first eight; more decompositions exist.

The digit sequence 1008 first appears in π at position 8,280 of the decimal expansion (the 8,280ordinal-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.
