Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661200, here are decompositions:

3 + 8661197 = 8661200
7 + 8661193 = 8661200
19 + 8661181 = 8661200
139 + 8661061 = 8661200
151 + 8661049 = 8661200
157 + 8661043 = 8661200
199 + 8661001 = 8661200
271 + 8660929 = 8661200

Showing the first eight; more decompositions exist.
