Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730736, here are decompositions:

107 + 8730629 = 8730736
263 + 8730473 = 8730736
269 + 8730467 = 8730736
359 + 8730377 = 8730736
383 + 8730353 = 8730736
449 + 8730287 = 8730736
467 + 8730269 = 8730736
479 + 8730257 = 8730736

Showing the first eight; more decompositions exist.
