Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020778, here are decompositions:

71 + 1020707 = 1020778
89 + 1020689 = 1020778
179 + 1020599 = 1020778
347 + 1020431 = 1020778
359 + 1020419 = 1020778
389 + 1020389 = 1020778
449 + 1020329 = 1020778
509 + 1020269 = 1020778

Showing the first eight; more decompositions exist.
