Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020784, here are decompositions:

5 + 1020779 = 1020784
41 + 1020743 = 1020784
101 + 1020683 = 1020784
227 + 1020557 = 1020784
293 + 1020491 = 1020784
353 + 1020431 = 1020784
383 + 1020401 = 1020784
431 + 1020353 = 1020784

Showing the first eight; more decompositions exist.
