Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728970, here are decompositions:

7 + 8728963 = 8728970
43 + 8728927 = 8728970
67 + 8728903 = 8728970
73 + 8728897 = 8728970
163 + 8728807 = 8728970
307 + 8728663 = 8728970
373 + 8728597 = 8728970
379 + 8728591 = 8728970

Showing the first eight; more decompositions exist.
