Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718626, here are decompositions:

139 + 8718487 = 8718626
157 + 8718469 = 8718626
199 + 8718427 = 8718626
277 + 8718349 = 8718626
283 + 8718343 = 8718626
313 + 8718313 = 8718626
349 + 8718277 = 8718626
379 + 8718247 = 8718626

Showing the first eight; more decompositions exist.
