Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742880, here are decompositions:

23 + 8742857 = 8742880
59 + 8742821 = 8742880
101 + 8742779 = 8742880
191 + 8742689 = 8742880
227 + 8742653 = 8742880
257 + 8742623 = 8742880
383 + 8742497 = 8742880
431 + 8742449 = 8742880

Showing the first eight; more decompositions exist.
