Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740786, here are decompositions:

3 + 8740783 = 8740786
23 + 8740763 = 8740786
29 + 8740757 = 8740786
59 + 8740727 = 8740786
107 + 8740679 = 8740786
137 + 8740649 = 8740786
179 + 8740607 = 8740786
227 + 8740559 = 8740786

Showing the first eight; more decompositions exist.
