Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688650, here are decompositions:

37 + 8688613 = 8688650
43 + 8688607 = 8688650
67 + 8688583 = 8688650
73 + 8688577 = 8688650
79 + 8688571 = 8688650
97 + 8688553 = 8688650
181 + 8688469 = 8688650
241 + 8688409 = 8688650

Showing the first eight; more decompositions exist.
