Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8006, here are decompositions:
- 13 + 7993 = 8006
- 43 + 7963 = 8006
- 73 + 7933 = 8006
- 79 + 7927 = 8006
- 127 + 7879 = 8006
- 139 + 7867 = 8006
- 283 + 7723 = 8006
- 307 + 7699 = 8006
Showing the first eight; more decompositions exist.

The digit sequence 8006 first appears in π at position 1,835 of the decimal expansion (the 1,835ordinal-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.
