Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601978, here are decompositions:

17 + 8601961 = 8601978
31 + 8601947 = 8601978
41 + 8601937 = 8601978
61 + 8601917 = 8601978
71 + 8601907 = 8601978
101 + 8601877 = 8601978
109 + 8601869 = 8601978
157 + 8601821 = 8601978

Showing the first eight; more decompositions exist.
