Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626406, here are decompositions:

109 + 8626297 = 8626406
157 + 8626249 = 8626406
163 + 8626243 = 8626406
277 + 8626129 = 8626406
307 + 8626099 = 8626406
409 + 8625997 = 8626406
433 + 8625973 = 8626406
619 + 8625787 = 8626406

Showing the first eight; more decompositions exist.
