Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179628, here are decompositions:

5 + 179623 = 179628
37 + 179591 = 179628
47 + 179581 = 179628
79 + 179549 = 179628
101 + 179527 = 179628
109 + 179519 = 179628
131 + 179497 = 179628
149 + 179479 = 179628

Showing the first eight; more decompositions exist.
