Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626664, here are decompositions:

43 + 8626621 = 8626664
61 + 8626603 = 8626664
157 + 8626507 = 8626664
367 + 8626297 = 8626664
421 + 8626243 = 8626664
523 + 8626141 = 8626664
601 + 8626063 = 8626664
691 + 8625973 = 8626664

Showing the first eight; more decompositions exist.
