Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179658, here are decompositions:

7 + 179651 = 179658
67 + 179591 = 179658
79 + 179579 = 179658
109 + 179549 = 179658
131 + 179527 = 179658
139 + 179519 = 179658
179 + 179479 = 179658
197 + 179461 = 179658

Showing the first eight; more decompositions exist.
