Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730646, here are decompositions:

17 + 8730629 = 8730646
173 + 8730473 = 8730646
179 + 8730467 = 8730646
269 + 8730377 = 8730646
293 + 8730353 = 8730646
359 + 8730287 = 8730646
383 + 8730263 = 8730646
389 + 8730257 = 8730646

Showing the first eight; more decompositions exist.
