Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665042, here are decompositions:

3 + 8665039 = 8665042
11 + 8665031 = 8665042
83 + 8664959 = 8665042
101 + 8664941 = 8665042
173 + 8664869 = 8665042
179 + 8664863 = 8665042
251 + 8664791 = 8665042
311 + 8664731 = 8665042

Showing the first eight; more decompositions exist.
