Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3844, here are decompositions:
- 11 + 3833 = 3844
- 23 + 3821 = 3844
- 41 + 3803 = 3844
- 47 + 3797 = 3844
- 83 + 3761 = 3844
- 167 + 3677 = 3844
- 173 + 3671 = 3844
- 227 + 3617 = 3844
Showing the first eight; more decompositions exist.

The digit sequence 3844 first appears in π at position 123 of the decimal expansion (the 123ordinal-suffix:rd 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.
