Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729182, here are decompositions:

3 + 8729179 = 8729182
41 + 8729141 = 8729182
83 + 8729099 = 8729182
89 + 8729093 = 8729182
101 + 8729081 = 8729182
131 + 8729051 = 8729182
149 + 8729033 = 8729182
239 + 8728943 = 8729182

Showing the first eight; more decompositions exist.
