Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712780, here are decompositions:

19 + 8712761 = 8712780
23 + 8712757 = 8712780
29 + 8712751 = 8712780
31 + 8712749 = 8712780
53 + 8712727 = 8712780
67 + 8712713 = 8712780
71 + 8712709 = 8712780
79 + 8712701 = 8712780

Showing the first eight; more decompositions exist.
