Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493156, here are decompositions:

17 + 493139 = 493156
23 + 493133 = 493156
29 + 493127 = 493156
47 + 493109 = 493156
89 + 493067 = 493156
107 + 493049 = 493156
113 + 493043 = 493156
263 + 492893 = 493156

Showing the first eight; more decompositions exist.
