Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661022, here are decompositions:

53 + 8660969 = 8661022
89 + 8660933 = 8661022
101 + 8660921 = 8661022
113 + 8660909 = 8661022
131 + 8660891 = 8661022
269 + 8660753 = 8661022
281 + 8660741 = 8661022
443 + 8660579 = 8661022

Showing the first eight; more decompositions exist.
