Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1004, here are decompositions:
- 7 + 997 = 1004
- 13 + 991 = 1004
- 37 + 967 = 1004
- 67 + 937 = 1004
- 97 + 907 = 1004
- 127 + 877 = 1004
- 151 + 853 = 1004
- 181 + 823 = 1004
Showing the first eight; more decompositions exist.

The digit sequence 1004 first appears in π at position 3,848 of the decimal expansion (the 3,848ordinal-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.
