Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649926, here are decompositions:

73 + 8649853 = 8649926
79 + 8649847 = 8649926
163 + 8649763 = 8649926
223 + 8649703 = 8649926
409 + 8649517 = 8649926
457 + 8649469 = 8649926
463 + 8649463 = 8649926
577 + 8649349 = 8649926

Showing the first eight; more decompositions exist.
