Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707790, here are decompositions:

37 + 8707753 = 8707790
43 + 8707747 = 8707790
79 + 8707711 = 8707790
103 + 8707687 = 8707790
139 + 8707651 = 8707790
199 + 8707591 = 8707790
211 + 8707579 = 8707790
313 + 8707477 = 8707790

Showing the first eight; more decompositions exist.
