Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729162, here are decompositions:

31 + 8729131 = 8729162
103 + 8729059 = 8729162
109 + 8729053 = 8729162
193 + 8728969 = 8729162
199 + 8728963 = 8729162
241 + 8728921 = 8729162
313 + 8728849 = 8729162
499 + 8728663 = 8729162

Showing the first eight; more decompositions exist.
