Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538628, here are decompositions:

7 + 538621 = 538628
31 + 538597 = 538628
61 + 538567 = 538628
67 + 538561 = 538628
109 + 538519 = 538628
157 + 538471 = 538628
229 + 538399 = 538628
271 + 538357 = 538628

Showing the first eight; more decompositions exist.
