Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738286, here are decompositions:

5 + 8738281 = 8738286
13 + 8738273 = 8738286
23 + 8738263 = 8738286
47 + 8738239 = 8738286
59 + 8738227 = 8738286
157 + 8738129 = 8738286
163 + 8738123 = 8738286
197 + 8738089 = 8738286

Showing the first eight; more decompositions exist.
