Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3612, here are decompositions:

5 + 3607 = 3612
19 + 3593 = 3612
29 + 3583 = 3612
31 + 3581 = 3612
41 + 3571 = 3612
53 + 3559 = 3612
71 + 3541 = 3612
73 + 3539 = 3612

Showing the first eight; more decompositions exist.
