Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1056390, here are decompositions:

11 + 1056379 = 1056390
17 + 1056373 = 1056390
19 + 1056371 = 1056390
29 + 1056361 = 1056390
37 + 1056353 = 1056390
43 + 1056347 = 1056390
67 + 1056323 = 1056390
73 + 1056317 = 1056390

Showing the first eight; more decompositions exist.
