Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029490, here are decompositions:

3 + 1029487 = 1029490
17 + 1029473 = 1029490
23 + 1029467 = 1029490
83 + 1029407 = 1029490
107 + 1029383 = 1029490
131 + 1029359 = 1029490
149 + 1029341 = 1029490
167 + 1029323 = 1029490

Showing the first eight; more decompositions exist.
