Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624490, here are decompositions:

13 + 8624477 = 8624490
31 + 8624459 = 8624490
41 + 8624449 = 8624490
97 + 8624393 = 8624490
107 + 8624383 = 8624490
137 + 8624353 = 8624490
163 + 8624327 = 8624490
167 + 8624323 = 8624490

Showing the first eight; more decompositions exist.
