Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027720, here are decompositions:

3 + 1027717 = 1027720
17 + 1027703 = 1027720
41 + 1027679 = 1027720
107 + 1027613 = 1027720
173 + 1027547 = 1027720
227 + 1027493 = 1027720
233 + 1027487 = 1027720
293 + 1027427 = 1027720

Showing the first eight; more decompositions exist.
