Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718670, here are decompositions:

89 + 8718581 = 8718670
131 + 8718539 = 8718670
167 + 8718503 = 8718670
179 + 8718491 = 8718670
239 + 8718431 = 8718670
251 + 8718419 = 8718670
263 + 8718407 = 8718670
269 + 8718401 = 8718670

Showing the first eight; more decompositions exist.
