Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730490, here are decompositions:

3 + 8730487 = 8730490
17 + 8730473 = 8730490
23 + 8730467 = 8730490
113 + 8730377 = 8730490
137 + 8730353 = 8730490
149 + 8730341 = 8730490
179 + 8730311 = 8730490
227 + 8730263 = 8730490

Showing the first eight; more decompositions exist.
