Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622416, here are decompositions:

3 + 8622413 = 8622416
37 + 8622379 = 8622416
43 + 8622373 = 8622416
73 + 8622343 = 8622416
79 + 8622337 = 8622416
109 + 8622307 = 8622416
193 + 8622223 = 8622416
409 + 8622007 = 8622416

Showing the first eight; more decompositions exist.
