Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670340, here are decompositions:

59 + 8670281 = 8670340
83 + 8670257 = 8670340
101 + 8670239 = 8670340
149 + 8670191 = 8670340
233 + 8670107 = 8670340
251 + 8670089 = 8670340
269 + 8670071 = 8670340
311 + 8670029 = 8670340

Showing the first eight; more decompositions exist.
