Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048778, here are decompositions:

19 + 1048759 = 1048778
61 + 1048717 = 1048778
97 + 1048681 = 1048778
151 + 1048627 = 1048778
229 + 1048549 = 1048778
271 + 1048507 = 1048778
331 + 1048447 = 1048778
421 + 1048357 = 1048778

Showing the first eight; more decompositions exist.
