Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022156, here are decompositions:

19 + 1022137 = 1022156
43 + 1022113 = 1022156
73 + 1022083 = 1022156
97 + 1022059 = 1022156
103 + 1022053 = 1022156
139 + 1022017 = 1022156
193 + 1021963 = 1022156
277 + 1021879 = 1022156

Showing the first eight; more decompositions exist.
