Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742916, here are decompositions:

29 + 8742887 = 8742916
59 + 8742857 = 8742916
137 + 8742779 = 8742916
227 + 8742689 = 8742916
239 + 8742677 = 8742916
263 + 8742653 = 8742916
293 + 8742623 = 8742916
419 + 8742497 = 8742916

Showing the first eight; more decompositions exist.
