Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047220, here are decompositions:

23 + 1047197 = 1047220
47 + 1047173 = 1047220
89 + 1047131 = 1047220
101 + 1047119 = 1047220
113 + 1047107 = 1047220
131 + 1047089 = 1047220
179 + 1047041 = 1047220
227 + 1046993 = 1047220

Showing the first eight; more decompositions exist.
