Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021804, here are decompositions:

5 + 1021799 = 1021804
11 + 1021793 = 1021804
107 + 1021697 = 1021804
131 + 1021673 = 1021804
227 + 1021577 = 1021804
233 + 1021571 = 1021804
263 + 1021541 = 1021804
317 + 1021487 = 1021804

Showing the first eight; more decompositions exist.
