Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730210, here are decompositions:

29 + 8730181 = 8730210
53 + 8730157 = 8730210
59 + 8730151 = 8730210
61 + 8730149 = 8730210
107 + 8730103 = 8730210
127 + 8730083 = 8730210
197 + 8730013 = 8730210
211 + 8729999 = 8730210

Showing the first eight; more decompositions exist.
