Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003658, here are decompositions:

31 + 1003627 = 1003658
37 + 1003621 = 1003658
109 + 1003549 = 1003658
151 + 1003507 = 1003658
241 + 1003417 = 1003658
277 + 1003381 = 1003658
307 + 1003351 = 1003658
367 + 1003291 = 1003658

Showing the first eight; more decompositions exist.
