Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726780, here are decompositions:

3 + 8726777 = 8726780
19 + 8726761 = 8726780
43 + 8726737 = 8726780
67 + 8726713 = 8726780
103 + 8726677 = 8726780
109 + 8726671 = 8726780
193 + 8726587 = 8726780
211 + 8726569 = 8726780

Showing the first eight; more decompositions exist.
