Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680942, here are decompositions:

3 + 8680939 = 8680942
41 + 8680901 = 8680942
71 + 8680871 = 8680942
131 + 8680811 = 8680942
173 + 8680769 = 8680942
251 + 8680691 = 8680942
311 + 8680631 = 8680942
359 + 8680583 = 8680942

Showing the first eight; more decompositions exist.
