Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8694218, here are decompositions:

7 + 8694211 = 8694218
109 + 8694109 = 8694218
139 + 8694079 = 8694218
199 + 8694019 = 8694218
271 + 8693947 = 8694218
277 + 8693941 = 8694218
307 + 8693911 = 8694218
541 + 8693677 = 8694218

Showing the first eight; more decompositions exist.
