Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690528, here are decompositions:

151 + 8690377 = 8690528
157 + 8690371 = 8690528
211 + 8690317 = 8690528
307 + 8690221 = 8690528
337 + 8690191 = 8690528
409 + 8690119 = 8690528
439 + 8690089 = 8690528
487 + 8690041 = 8690528

Showing the first eight; more decompositions exist.
