Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 944890, here are decompositions:

3 + 944887 = 944890
17 + 944873 = 944890
113 + 944777 = 944890
173 + 944717 = 944890
179 + 944711 = 944890
239 + 944651 = 944890
269 + 944621 = 944890
281 + 944609 = 944890

Showing the first eight; more decompositions exist.
