Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022942, here are decompositions:

13 + 1022929 = 1022942
31 + 1022911 = 1022942
43 + 1022899 = 1022942
61 + 1022881 = 1022942
73 + 1022869 = 1022942
181 + 1022761 = 1022942
223 + 1022719 = 1022942
241 + 1022701 = 1022942

Showing the first eight; more decompositions exist.
