Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017808, here are decompositions:

59 + 1017749 = 1017808
89 + 1017719 = 1017808
191 + 1017617 = 1017808
257 + 1017551 = 1017808
269 + 1017539 = 1017808
359 + 1017449 = 1017808
431 + 1017377 = 1017808
461 + 1017347 = 1017808

Showing the first eight; more decompositions exist.
