Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620290, here are decompositions:

13 + 8620277 = 8620290
23 + 8620267 = 8620290
31 + 8620259 = 8620290
59 + 8620231 = 8620290
71 + 8620219 = 8620290
73 + 8620217 = 8620290
79 + 8620211 = 8620290
101 + 8620189 = 8620290

Showing the first eight; more decompositions exist.
