Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027220, here are decompositions:

13 + 1027207 = 1027220
31 + 1027189 = 1027220
67 + 1027153 = 1027220
193 + 1027027 = 1027220
241 + 1026979 = 1027220
277 + 1026943 = 1027220
307 + 1026913 = 1027220
367 + 1026853 = 1027220

Showing the first eight; more decompositions exist.
