Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022620, here are decompositions:

29 + 1022591 = 1022620
47 + 1022573 = 1022620
89 + 1022531 = 1022620
101 + 1022519 = 1022620
107 + 1022513 = 1022620
113 + 1022507 = 1022620
191 + 1022429 = 1022620
233 + 1022387 = 1022620

Showing the first eight; more decompositions exist.
