Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690650, here are decompositions:

11 + 8690639 = 8690650
47 + 8690603 = 8690650
83 + 8690567 = 8690650
173 + 8690477 = 8690650
197 + 8690453 = 8690650
239 + 8690411 = 8690650
251 + 8690399 = 8690650
263 + 8690387 = 8690650

Showing the first eight; more decompositions exist.
