Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022272, here are decompositions:

23 + 1022249 = 1022272
29 + 1022243 = 1022272
71 + 1022201 = 1022272
89 + 1022183 = 1022272
131 + 1022141 = 1022272
149 + 1022123 = 1022272
239 + 1022033 = 1022272
311 + 1021961 = 1022272

Showing the first eight; more decompositions exist.
