Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103658, here are decompositions:

7 + 103651 = 103658
67 + 103591 = 103658
97 + 103561 = 103658
109 + 103549 = 103658
271 + 103387 = 103658
367 + 103291 = 103658
421 + 103237 = 103658
487 + 103171 = 103658

Showing the first eight; more decompositions exist.
