Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707658, here are decompositions:

7 + 8707651 = 8707658
67 + 8707591 = 8707658
79 + 8707579 = 8707658
181 + 8707477 = 8707658
229 + 8707429 = 8707658
307 + 8707351 = 8707658
331 + 8707327 = 8707658
439 + 8707219 = 8707658

Showing the first eight; more decompositions exist.
