Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661086, here are decompositions:

37 + 8661049 = 8661086
43 + 8661043 = 8661086
103 + 8660983 = 8661086
139 + 8660947 = 8661086
157 + 8660929 = 8661086
199 + 8660887 = 8661086
223 + 8660863 = 8661086
397 + 8660689 = 8661086

Showing the first eight; more decompositions exist.
