Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707820, here are decompositions:

3 + 8707817 = 8707820
67 + 8707753 = 8707820
73 + 8707747 = 8707820
109 + 8707711 = 8707820
151 + 8707669 = 8707820
229 + 8707591 = 8707820
241 + 8707579 = 8707820
283 + 8707537 = 8707820

Showing the first eight; more decompositions exist.
