Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656042, here are decompositions:

11 + 8656031 = 8656042
23 + 8656019 = 8656042
89 + 8655953 = 8656042
173 + 8655869 = 8656042
233 + 8655809 = 8656042
281 + 8655761 = 8656042
293 + 8655749 = 8656042
389 + 8655653 = 8656042

Showing the first eight; more decompositions exist.
