Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670748, here are decompositions:

5 + 8670743 = 8670748
137 + 8670611 = 8670748
197 + 8670551 = 8670748
239 + 8670509 = 8670748
257 + 8670491 = 8670748
467 + 8670281 = 8670748
491 + 8670257 = 8670748
509 + 8670239 = 8670748

Showing the first eight; more decompositions exist.
