Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047490, here are decompositions:

11 + 1047479 = 1047490
23 + 1047467 = 1047490
71 + 1047419 = 1047490
149 + 1047341 = 1047490
167 + 1047323 = 1047490
173 + 1047317 = 1047490
179 + 1047311 = 1047490
251 + 1047239 = 1047490

Showing the first eight; more decompositions exist.
