Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650, here are decompositions:

3 + 8647 = 8650
23 + 8627 = 8650
41 + 8609 = 8650
53 + 8597 = 8650
107 + 8543 = 8650
113 + 8537 = 8650
137 + 8513 = 8650
149 + 8501 = 8650

Showing the first eight; more decompositions exist.
