Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3646, here are decompositions:

3 + 3643 = 3646
23 + 3623 = 3646
29 + 3617 = 3646
53 + 3593 = 3646
89 + 3557 = 3646
107 + 3539 = 3646
113 + 3533 = 3646
179 + 3467 = 3646

Showing the first eight; more decompositions exist.
