Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986390, here are decompositions:

103 + 986287 = 986390
109 + 986281 = 986390
151 + 986239 = 986390
193 + 986197 = 986390
199 + 986191 = 986390
241 + 986149 = 986390
277 + 986113 = 986390
337 + 986053 = 986390

Showing the first eight; more decompositions exist.
