Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672978, here are decompositions:

31 + 8672947 = 8672978
109 + 8672869 = 8672978
157 + 8672821 = 8672978
199 + 8672779 = 8672978
211 + 8672767 = 8672978
271 + 8672707 = 8672978
331 + 8672647 = 8672978
337 + 8672641 = 8672978

Showing the first eight; more decompositions exist.
