Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67644, here are decompositions:
- 13 + 67631 = 67644
- 37 + 67607 = 67644
- 43 + 67601 = 67644
- 67 + 67577 = 67644
- 97 + 67547 = 67644
- 107 + 67537 = 67644
- 113 + 67531 = 67644
- 151 + 67493 = 67644
Showing the first eight; more decompositions exist.

The digit sequence 67644 first appears in π at position 148,366 of the decimal expansion (the 148,366ordinal-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.
