Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022722, here are decompositions:

3 + 1022719 = 1022722
83 + 1022639 = 1022722
89 + 1022633 = 1022722
131 + 1022591 = 1022722
149 + 1022573 = 1022722
191 + 1022531 = 1022722
293 + 1022429 = 1022722
419 + 1022303 = 1022722

Showing the first eight; more decompositions exist.
