Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13650, here are decompositions:

17 + 13633 = 13650
23 + 13627 = 13650
31 + 13619 = 13650
37 + 13613 = 13650
53 + 13597 = 13650
59 + 13591 = 13650
73 + 13577 = 13650
83 + 13567 = 13650

Showing the first eight; more decompositions exist.
