Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624664, here are decompositions:

31 + 8624633 = 8624664
43 + 8624621 = 8624664
47 + 8624617 = 8624664
157 + 8624507 = 8624664
271 + 8624393 = 8624664
281 + 8624383 = 8624664
311 + 8624353 = 8624664
337 + 8624327 = 8624664

Showing the first eight; more decompositions exist.
