Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022408, here are decompositions:

19 + 1022389 = 1022408
31 + 1022377 = 1022408
67 + 1022341 = 1022408
157 + 1022251 = 1022408
199 + 1022209 = 1022408
229 + 1022179 = 1022408
241 + 1022167 = 1022408
271 + 1022137 = 1022408

Showing the first eight; more decompositions exist.
