Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022200, here are decompositions:

17 + 1022183 = 1022200
59 + 1022141 = 1022200
71 + 1022129 = 1022200
167 + 1022033 = 1022200
227 + 1021973 = 1022200
239 + 1021961 = 1022200
281 + 1021919 = 1022200
293 + 1021907 = 1022200

Showing the first eight; more decompositions exist.
