Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3678, here are decompositions:
- 5 + 3673 = 3678
- 7 + 3671 = 3678
- 19 + 3659 = 3678
- 41 + 3637 = 3678
- 47 + 3631 = 3678
- 61 + 3617 = 3678
- 71 + 3607 = 3678
- 97 + 3581 = 3678
Showing the first eight; more decompositions exist.

The digit sequence 3678 first appears in π at position 349 of the decimal expansion (the 349ordinal-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.
