Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143628, here are decompositions:

11 + 143617 = 143628
19 + 143609 = 143628
59 + 143569 = 143628
61 + 143567 = 143628
101 + 143527 = 143628
109 + 143519 = 143628
127 + 143501 = 143628
139 + 143489 = 143628

Showing the first eight; more decompositions exist.
