Goldbach decomposition

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.
