Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706990, here are decompositions:

7 + 8706983 = 8706990
11 + 8706979 = 8706990
23 + 8706967 = 8706990
29 + 8706961 = 8706990
37 + 8706953 = 8706990
43 + 8706947 = 8706990
53 + 8706937 = 8706990
109 + 8706881 = 8706990

Showing the first eight; more decompositions exist.
