Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626942, here are decompositions:

41 + 8626901 = 8626942
101 + 8626841 = 8626942
131 + 8626811 = 8626942
179 + 8626763 = 8626942
251 + 8626691 = 8626942
449 + 8626493 = 8626942
521 + 8626421 = 8626942
593 + 8626349 = 8626942

Showing the first eight; more decompositions exist.
