Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670628, here are decompositions:

17 + 8670611 = 8670628
137 + 8670491 = 8670628
257 + 8670371 = 8670628
347 + 8670281 = 8670628
389 + 8670239 = 8670628
431 + 8670197 = 8670628
521 + 8670107 = 8670628
557 + 8670071 = 8670628

Showing the first eight; more decompositions exist.
