Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623970, here are decompositions:

7 + 8623963 = 8623970
31 + 8623939 = 8623970
67 + 8623903 = 8623970
73 + 8623897 = 8623970
127 + 8623843 = 8623970
139 + 8623831 = 8623970
163 + 8623807 = 8623970
241 + 8623729 = 8623970

Showing the first eight; more decompositions exist.
