Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707156, here are decompositions:

53 + 8707103 = 8707156
149 + 8707007 = 8707156
173 + 8706983 = 8707156
449 + 8706707 = 8707156
509 + 8706647 = 8707156
569 + 8706587 = 8707156
587 + 8706569 = 8707156
599 + 8706557 = 8707156

Showing the first eight; more decompositions exist.
