Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9644, here are decompositions:
- 13 + 9631 = 9644
- 31 + 9613 = 9644
- 43 + 9601 = 9644
- 97 + 9547 = 9644
- 181 + 9463 = 9644
- 211 + 9433 = 9644
- 223 + 9421 = 9644
- 241 + 9403 = 9644
Showing the first eight; more decompositions exist.

The digit sequence 9644 first appears in π at position 180 of the decimal expansion (the 180ordinal-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.
