Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730512, here are decompositions:

163 + 8730349 = 8730512
181 + 8730331 = 8730512
229 + 8730283 = 8730512
283 + 8730229 = 8730512
331 + 8730181 = 8730512
409 + 8730103 = 8730512
421 + 8730091 = 8730512
463 + 8730049 = 8730512

Showing the first eight; more decompositions exist.
