Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026778, here are decompositions:

17 + 1026761 = 1026778
101 + 1026677 = 1026778
191 + 1026587 = 1026778
197 + 1026581 = 1026778
257 + 1026521 = 1026778
419 + 1026359 = 1026778
479 + 1026299 = 1026778
521 + 1026257 = 1026778

Showing the first eight; more decompositions exist.
