Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10628, here are decompositions:

31 + 10597 = 10628
61 + 10567 = 10628
97 + 10531 = 10628
127 + 10501 = 10628
151 + 10477 = 10628
199 + 10429 = 10628
229 + 10399 = 10628
271 + 10357 = 10628

Showing the first eight; more decompositions exist.
