Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707278, here are decompositions:

5 + 8707273 = 8707278
37 + 8707241 = 8707278
59 + 8707219 = 8707278
71 + 8707207 = 8707278
89 + 8707189 = 8707278
131 + 8707147 = 8707278
241 + 8707037 = 8707278
257 + 8707021 = 8707278

Showing the first eight; more decompositions exist.
