Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8696978, here are decompositions:

61 + 8696917 = 8696978
211 + 8696767 = 8696978
229 + 8696749 = 8696978
307 + 8696671 = 8696978
349 + 8696629 = 8696978
397 + 8696581 = 8696978
457 + 8696521 = 8696978
541 + 8696437 = 8696978

Showing the first eight; more decompositions exist.
