Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621774, here are decompositions:

67 + 8621707 = 8621774
97 + 8621677 = 8621774
151 + 8621623 = 8621774
157 + 8621617 = 8621774
193 + 8621581 = 8621774
223 + 8621551 = 8621774
283 + 8621491 = 8621774
307 + 8621467 = 8621774

Showing the first eight; more decompositions exist.
