Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023406, here are decompositions:

17 + 1023389 = 1023406
53 + 1023353 = 1023406
89 + 1023317 = 1023406
107 + 1023299 = 1023406
149 + 1023257 = 1023406
179 + 1023227 = 1023406
233 + 1023173 = 1023406
239 + 1023167 = 1023406

Showing the first eight; more decompositions exist.
