Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022148, here are decompositions:

7 + 1022141 = 1022148
11 + 1022137 = 1022148
19 + 1022129 = 1022148
89 + 1022059 = 1022148
131 + 1022017 = 1022148
137 + 1022011 = 1022148
229 + 1021919 = 1022148
241 + 1021907 = 1022148

Showing the first eight; more decompositions exist.
