Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022238, here are decompositions:

29 + 1022209 = 1022238
37 + 1022201 = 1022238
47 + 1022191 = 1022238
59 + 1022179 = 1022238
71 + 1022167 = 1022238
97 + 1022141 = 1022238
101 + 1022137 = 1022238
109 + 1022129 = 1022238

Showing the first eight; more decompositions exist.
