Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039390, here are decompositions:

3 + 1039387 = 1039390
41 + 1039349 = 1039390
47 + 1039343 = 1039390
83 + 1039307 = 1039390
101 + 1039289 = 1039390
251 + 1039139 = 1039390
263 + 1039127 = 1039390
281 + 1039109 = 1039390

Showing the first eight; more decompositions exist.
