Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738970, here are decompositions:

7 + 8738963 = 8738970
13 + 8738957 = 8738970
41 + 8738929 = 8738970
89 + 8738881 = 8738970
127 + 8738843 = 8738970
131 + 8738839 = 8738970
157 + 8738813 = 8738970
211 + 8738759 = 8738970

Showing the first eight; more decompositions exist.
