Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667278, here are decompositions:

7 + 8667271 = 8667278
127 + 8667151 = 8667278
157 + 8667121 = 8667278
199 + 8667079 = 8667278
397 + 8666881 = 8667278
439 + 8666839 = 8667278
787 + 8666491 = 8667278
859 + 8666419 = 8667278

Showing the first eight; more decompositions exist.
