Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017778, here are decompositions:

29 + 1017749 = 1017778
59 + 1017719 = 1017778
131 + 1017647 = 1017778
227 + 1017551 = 1017778
239 + 1017539 = 1017778
401 + 1017377 = 1017778
431 + 1017347 = 1017778
449 + 1017329 = 1017778

Showing the first eight; more decompositions exist.
