Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670280, here are decompositions:

23 + 8670257 = 8670280
41 + 8670239 = 8670280
83 + 8670197 = 8670280
89 + 8670191 = 8670280
173 + 8670107 = 8670280
191 + 8670089 = 8670280
239 + 8670041 = 8670280
251 + 8670029 = 8670280

Showing the first eight; more decompositions exist.
