Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738946, here are decompositions:

17 + 8738929 = 8738946
103 + 8738843 = 8738946
107 + 8738839 = 8738946
109 + 8738837 = 8738946
137 + 8738809 = 8738946
163 + 8738783 = 8738946
179 + 8738767 = 8738946
233 + 8738713 = 8738946

Showing the first eight; more decompositions exist.
