Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621124, here are decompositions:

23 + 8621101 = 8621124
37 + 8621087 = 8621124
41 + 8621083 = 8621124
47 + 8621077 = 8621124
73 + 8621051 = 8621124
107 + 8621017 = 8621124
131 + 8620993 = 8621124
151 + 8620973 = 8621124

Showing the first eight; more decompositions exist.
