Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022150, here are decompositions:

13 + 1022137 = 1022150
37 + 1022113 = 1022150
67 + 1022083 = 1022150
79 + 1022071 = 1022150
97 + 1022053 = 1022150
139 + 1022011 = 1022150
271 + 1021879 = 1022150
313 + 1021837 = 1022150

Showing the first eight; more decompositions exist.
