Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613290, here are decompositions:

61 + 8613229 = 8613290
79 + 8613211 = 8613290
109 + 8613181 = 8613290
163 + 8613127 = 8613290
199 + 8613091 = 8613290
271 + 8613019 = 8613290
307 + 8612983 = 8613290
331 + 8612959 = 8613290

Showing the first eight; more decompositions exist.
