Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613278, here are decompositions:

67 + 8613211 = 8613278
97 + 8613181 = 8613278
151 + 8613127 = 8613278
277 + 8613001 = 8613278
337 + 8612941 = 8613278
439 + 8612839 = 8613278
547 + 8612731 = 8613278
571 + 8612707 = 8613278

Showing the first eight; more decompositions exist.
