Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610978, here are decompositions:

17 + 8610961 = 8610978
41 + 8610937 = 8610978
59 + 8610919 = 8610978
97 + 8610881 = 8610978
107 + 8610871 = 8610978
127 + 8610851 = 8610978
149 + 8610829 = 8610978
151 + 8610827 = 8610978

Showing the first eight; more decompositions exist.
