Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618738, here are decompositions:

157 + 8618581 = 8618738
181 + 8618557 = 8618738
409 + 8618329 = 8618738
421 + 8618317 = 8618738
487 + 8618251 = 8618738
607 + 8618131 = 8618738
619 + 8618119 = 8618738
631 + 8618107 = 8618738

Showing the first eight; more decompositions exist.
