Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156798, here are decompositions:

17 + 156781 = 156798
71 + 156727 = 156798
79 + 156719 = 156798
107 + 156691 = 156798
127 + 156671 = 156798
139 + 156659 = 156798
157 + 156641 = 156798
167 + 156631 = 156798

Showing the first eight; more decompositions exist.
