Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707784, here are decompositions:

3 + 8707781 = 8707784
31 + 8707753 = 8707784
37 + 8707747 = 8707784
73 + 8707711 = 8707784
97 + 8707687 = 8707784
181 + 8707603 = 8707784
193 + 8707591 = 8707784
307 + 8707477 = 8707784

Showing the first eight; more decompositions exist.
