Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185630, here are decompositions:

31 + 185599 = 185630
37 + 185593 = 185630
61 + 185569 = 185630
73 + 185557 = 185630
79 + 185551 = 185630
97 + 185533 = 185630
103 + 185527 = 185630
139 + 185491 = 185630

Showing the first eight; more decompositions exist.
