Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746978, here are decompositions:

11 + 8746967 = 8746978
29 + 8746949 = 8746978
41 + 8746937 = 8746978
59 + 8746919 = 8746978
131 + 8746847 = 8746978
167 + 8746811 = 8746978
179 + 8746799 = 8746978
269 + 8746709 = 8746978

Showing the first eight; more decompositions exist.
