Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3846, here are decompositions:
- 13 + 3833 = 3846
- 23 + 3823 = 3846
- 43 + 3803 = 3846
- 53 + 3793 = 3846
- 67 + 3779 = 3846
- 79 + 3767 = 3846
- 107 + 3739 = 3846
- 113 + 3733 = 3846
Showing the first eight; more decompositions exist.

The digit sequence 3846 first appears in π at position 17 of the decimal expansion (the 17ordinal-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.
