Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022190, here are decompositions:

7 + 1022183 = 1022190
11 + 1022179 = 1022190
23 + 1022167 = 1022190
53 + 1022137 = 1022190
61 + 1022129 = 1022190
67 + 1022123 = 1022190
107 + 1022083 = 1022190
131 + 1022059 = 1022190

Showing the first eight; more decompositions exist.
