Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730186, here are decompositions:

5 + 8730181 = 8730186
29 + 8730157 = 8730186
37 + 8730149 = 8730186
83 + 8730103 = 8730186
103 + 8730083 = 8730186
109 + 8730077 = 8730186
137 + 8730049 = 8730186
173 + 8730013 = 8730186

Showing the first eight; more decompositions exist.
