Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707066, here are decompositions:

29 + 8707037 = 8707066
59 + 8707007 = 8707066
83 + 8706983 = 8707066
113 + 8706953 = 8707066
197 + 8706869 = 8707066
233 + 8706833 = 8707066
359 + 8706707 = 8707066
419 + 8706647 = 8707066

Showing the first eight; more decompositions exist.
