Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8694180, here are decompositions:

71 + 8694109 = 8694180
83 + 8694097 = 8694180
97 + 8694083 = 8694180
101 + 8694079 = 8694180
107 + 8694073 = 8694180
149 + 8694031 = 8694180
163 + 8694017 = 8694180
197 + 8693983 = 8694180

Showing the first eight; more decompositions exist.
