Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730730, here are decompositions:

101 + 8730629 = 8730730
257 + 8730473 = 8730730
263 + 8730467 = 8730730
353 + 8730377 = 8730730
389 + 8730341 = 8730730
419 + 8730311 = 8730730
443 + 8730287 = 8730730
461 + 8730269 = 8730730

Showing the first eight; more decompositions exist.
