Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022140, here are decompositions:

3 + 1022137 = 1022140
11 + 1022129 = 1022140
17 + 1022123 = 1022140
107 + 1022033 = 1022140
167 + 1021973 = 1022140
179 + 1021961 = 1022140
233 + 1021907 = 1022140
347 + 1021793 = 1022140

Showing the first eight; more decompositions exist.
