Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728976, here are decompositions:

7 + 8728969 = 8728976
13 + 8728963 = 8728976
73 + 8728903 = 8728976
79 + 8728897 = 8728976
127 + 8728849 = 8728976
313 + 8728663 = 8728976
349 + 8728627 = 8728976
367 + 8728609 = 8728976

Showing the first eight; more decompositions exist.
