Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706940, here are decompositions:

3 + 8706937 = 8706940
59 + 8706881 = 8706940
71 + 8706869 = 8706940
107 + 8706833 = 8706940
149 + 8706791 = 8706940
197 + 8706743 = 8706940
233 + 8706707 = 8706940
269 + 8706671 = 8706940

Showing the first eight; more decompositions exist.
