Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039420, here are decompositions:

71 + 1039349 = 1039420
113 + 1039307 = 1039420
131 + 1039289 = 1039420
191 + 1039229 = 1039420
233 + 1039187 = 1039420
251 + 1039169 = 1039420
281 + 1039139 = 1039420
293 + 1039127 = 1039420

Showing the first eight; more decompositions exist.
