Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625878, here are decompositions:

67 + 8625811 = 8625878
229 + 8625649 = 8625878
241 + 8625637 = 8625878
337 + 8625541 = 8625878
577 + 8625301 = 8625878
631 + 8625247 = 8625878
691 + 8625187 = 8625878
757 + 8625121 = 8625878

Showing the first eight; more decompositions exist.
