Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730090, here are decompositions:

7 + 8730083 = 8730090
13 + 8730077 = 8730090
23 + 8730067 = 8730090
41 + 8730049 = 8730090
107 + 8729983 = 8730090
113 + 8729977 = 8730090
151 + 8729939 = 8730090
167 + 8729923 = 8730090

Showing the first eight; more decompositions exist.
