Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627290, here are decompositions:

47 + 8627243 = 8627290
137 + 8627153 = 8627290
149 + 8627141 = 8627290
179 + 8627111 = 8627290
233 + 8627057 = 8627290
239 + 8627051 = 8627290
257 + 8627033 = 8627290
389 + 8626901 = 8627290

Showing the first eight; more decompositions exist.
