Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661122, here are decompositions:

3 + 8661119 = 8661122
61 + 8661061 = 8661122
73 + 8661049 = 8661122
79 + 8661043 = 8661122
139 + 8660983 = 8661122
193 + 8660929 = 8661122
433 + 8660689 = 8661122
439 + 8660683 = 8661122

Showing the first eight; more decompositions exist.
