Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730390, here are decompositions:

13 + 8730377 = 8730390
37 + 8730353 = 8730390
41 + 8730349 = 8730390
47 + 8730343 = 8730390
59 + 8730331 = 8730390
79 + 8730311 = 8730390
83 + 8730307 = 8730390
103 + 8730287 = 8730390

Showing the first eight; more decompositions exist.
