Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617924, here are decompositions:

47 + 8617877 = 8617924
53 + 8617871 = 8617924
101 + 8617823 = 8617924
137 + 8617787 = 8617924
401 + 8617523 = 8617924
563 + 8617361 = 8617924
647 + 8617277 = 8617924
827 + 8617097 = 8617924

Showing the first eight; more decompositions exist.
