Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3616, here are decompositions:

3 + 3613 = 3616
23 + 3593 = 3616
59 + 3557 = 3616
83 + 3533 = 3616
89 + 3527 = 3616
149 + 3467 = 3616
167 + 3449 = 3616
227 + 3389 = 3616

Showing the first eight; more decompositions exist.
