Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715990, here are decompositions:

13 + 8715977 = 8715990
29 + 8715961 = 8715990
43 + 8715947 = 8715990
53 + 8715937 = 8715990
83 + 8715907 = 8715990
89 + 8715901 = 8715990
103 + 8715887 = 8715990
109 + 8715881 = 8715990

Showing the first eight; more decompositions exist.
