Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730222, here are decompositions:

41 + 8730181 = 8730222
71 + 8730151 = 8730222
73 + 8730149 = 8730222
131 + 8730091 = 8730222
139 + 8730083 = 8730222
173 + 8730049 = 8730222
223 + 8729999 = 8730222
239 + 8729983 = 8730222

Showing the first eight; more decompositions exist.
