Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700390, here are decompositions:

7 + 8700383 = 8700390
29 + 8700361 = 8700390
37 + 8700353 = 8700390
103 + 8700287 = 8700390
107 + 8700283 = 8700390
109 + 8700281 = 8700390
137 + 8700253 = 8700390
151 + 8700239 = 8700390

Showing the first eight; more decompositions exist.
