Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024778, here are decompositions:

67 + 1024711 = 1024778
109 + 1024669 = 1024778
199 + 1024579 = 1024778
367 + 1024411 = 1024778
379 + 1024399 = 1024778
421 + 1024357 = 1024778
439 + 1024339 = 1024778
457 + 1024321 = 1024778

Showing the first eight; more decompositions exist.
