Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 652, here are decompositions:

5 + 647 = 652
11 + 641 = 652
53 + 599 = 652
59 + 593 = 652
83 + 569 = 652
89 + 563 = 652
131 + 521 = 652
149 + 503 = 652

Showing the first eight; more decompositions exist.
