Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730228, here are decompositions:

47 + 8730181 = 8730228
71 + 8730157 = 8730228
79 + 8730149 = 8730228
137 + 8730091 = 8730228
151 + 8730077 = 8730228
179 + 8730049 = 8730228
229 + 8729999 = 8730228
251 + 8729977 = 8730228

Showing the first eight; more decompositions exist.
