Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103628, here are decompositions:

37 + 103591 = 103628
61 + 103567 = 103628
67 + 103561 = 103628
79 + 103549 = 103628
157 + 103471 = 103628
229 + 103399 = 103628
241 + 103387 = 103628
271 + 103357 = 103628

Showing the first eight; more decompositions exist.
