Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730724, here are decompositions:

113 + 8730611 = 8730724
251 + 8730473 = 8730724
257 + 8730467 = 8730724
347 + 8730377 = 8730724
383 + 8730341 = 8730724
461 + 8730263 = 8730724
467 + 8730257 = 8730724
641 + 8730083 = 8730724

Showing the first eight; more decompositions exist.
