Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730320, here are decompositions:

13 + 8730307 = 8730320
37 + 8730283 = 8730320
139 + 8730181 = 8730320
163 + 8730157 = 8730320
229 + 8730091 = 8730320
271 + 8730049 = 8730320
307 + 8730013 = 8730320
337 + 8729983 = 8730320

Showing the first eight; more decompositions exist.
