Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670388, here are decompositions:

17 + 8670371 = 8670388
107 + 8670281 = 8670388
131 + 8670257 = 8670388
149 + 8670239 = 8670388
191 + 8670197 = 8670388
197 + 8670191 = 8670388
281 + 8670107 = 8670388
317 + 8670071 = 8670388

Showing the first eight; more decompositions exist.
