Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022168, here are decompositions:

31 + 1022137 = 1022168
97 + 1022071 = 1022168
109 + 1022059 = 1022168
151 + 1022017 = 1022168
157 + 1022011 = 1022168
271 + 1021897 = 1022168
307 + 1021861 = 1022168
331 + 1021837 = 1022168

Showing the first eight; more decompositions exist.
