Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742976, here are decompositions:

3 + 8742973 = 8742976
59 + 8742917 = 8742976
89 + 8742887 = 8742976
197 + 8742779 = 8742976
353 + 8742623 = 8742976
479 + 8742497 = 8742976
617 + 8742359 = 8742976
659 + 8742317 = 8742976

Showing the first eight; more decompositions exist.
