Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022172, here are decompositions:

5 + 1022167 = 1022172
31 + 1022141 = 1022172
43 + 1022129 = 1022172
59 + 1022113 = 1022172
89 + 1022083 = 1022172
101 + 1022071 = 1022172
113 + 1022059 = 1022172
139 + 1022033 = 1022172

Showing the first eight; more decompositions exist.
