Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011490, here are decompositions:

47 + 1011443 = 1011490
59 + 1011431 = 1011490
83 + 1011407 = 1011490
113 + 1011377 = 1011490
131 + 1011359 = 1011490
251 + 1011239 = 1011490
257 + 1011233 = 1011490
269 + 1011221 = 1011490

Showing the first eight; more decompositions exist.
