Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707042, here are decompositions:

5 + 8707037 = 8707042
11 + 8707031 = 8707042
59 + 8706983 = 8707042
89 + 8706953 = 8707042
173 + 8706869 = 8707042
251 + 8706791 = 8707042
431 + 8706611 = 8707042
563 + 8706479 = 8707042

Showing the first eight; more decompositions exist.
