Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022158, here are decompositions:

17 + 1022141 = 1022158
29 + 1022129 = 1022158
197 + 1021961 = 1022158
239 + 1021919 = 1022158
251 + 1021907 = 1022158
359 + 1021799 = 1022158
461 + 1021697 = 1022158
587 + 1021571 = 1022158

Showing the first eight; more decompositions exist.
