Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617020, here are decompositions:

19 + 8617001 = 8617020
23 + 8616997 = 8617020
29 + 8616991 = 8617020
31 + 8616989 = 8617020
73 + 8616947 = 8617020
101 + 8616919 = 8617020
103 + 8616917 = 8617020
107 + 8616913 = 8617020

Showing the first eight; more decompositions exist.
