Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718718, here are decompositions:

137 + 8718581 = 8718718
179 + 8718539 = 8718718
227 + 8718491 = 8718718
257 + 8718461 = 8718718
311 + 8718407 = 8718718
317 + 8718401 = 8718718
467 + 8718251 = 8718718
521 + 8718197 = 8718718

Showing the first eight; more decompositions exist.
