Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715618, here are decompositions:

17 + 8715601 = 8715618
29 + 8715589 = 8715618
31 + 8715587 = 8715618
59 + 8715559 = 8715618
167 + 8715451 = 8715618
257 + 8715361 = 8715618
269 + 8715349 = 8715618
271 + 8715347 = 8715618

Showing the first eight; more decompositions exist.
