Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3630, here are decompositions:

7 + 3623 = 3630
13 + 3617 = 3630
17 + 3613 = 3630
23 + 3607 = 3630
37 + 3593 = 3630
47 + 3583 = 3630
59 + 3571 = 3630
71 + 3559 = 3630

Showing the first eight; more decompositions exist.
