Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707904, here are decompositions:

31 + 8707873 = 8707904
43 + 8707861 = 8707904
61 + 8707843 = 8707904
67 + 8707837 = 8707904
151 + 8707753 = 8707904
157 + 8707747 = 8707904
193 + 8707711 = 8707904
313 + 8707591 = 8707904

Showing the first eight; more decompositions exist.
