Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022680, here are decompositions:

3 + 1022677 = 1022680
41 + 1022639 = 1022680
47 + 1022633 = 1022680
89 + 1022591 = 1022680
107 + 1022573 = 1022680
149 + 1022531 = 1022680
167 + 1022513 = 1022680
173 + 1022507 = 1022680

Showing the first eight; more decompositions exist.
