Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658918, here are decompositions:

7 + 8658911 = 8658918
31 + 8658887 = 8658918
41 + 8658877 = 8658918
71 + 8658847 = 8658918
89 + 8658829 = 8658918
179 + 8658739 = 8658918
239 + 8658679 = 8658918
241 + 8658677 = 8658918

Showing the first eight; more decompositions exist.
