Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730212, here are decompositions:

31 + 8730181 = 8730212
61 + 8730151 = 8730212
109 + 8730103 = 8730212
163 + 8730049 = 8730212
199 + 8730013 = 8730212
229 + 8729983 = 8730212
331 + 8729881 = 8730212
373 + 8729839 = 8730212

Showing the first eight; more decompositions exist.
