Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042778, here are decompositions:

19 + 1042759 = 1042778
97 + 1042681 = 1042778
181 + 1042597 = 1042778
379 + 1042399 = 1042778
397 + 1042381 = 1042778
409 + 1042369 = 1042778
421 + 1042357 = 1042778
691 + 1042087 = 1042778

Showing the first eight; more decompositions exist.
