Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697278, here are decompositions:

151 + 8697127 = 8697278
181 + 8697097 = 8697278
229 + 8697049 = 8697278
241 + 8697037 = 8697278
487 + 8696791 = 8697278
607 + 8696671 = 8697278
661 + 8696617 = 8697278
757 + 8696521 = 8697278

Showing the first eight; more decompositions exist.
