Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747218, here are decompositions:

5 + 8747213 = 8747218
47 + 8747171 = 8747218
59 + 8747159 = 8747218
107 + 8747111 = 8747218
239 + 8746979 = 8747218
251 + 8746967 = 8747218
269 + 8746949 = 8747218
281 + 8746937 = 8747218

Showing the first eight; more decompositions exist.
