Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 944820, here are decompositions:

17 + 944803 = 944820
43 + 944777 = 944820
47 + 944773 = 944820
89 + 944731 = 944820
103 + 944717 = 944820
109 + 944711 = 944820
131 + 944689 = 944820
199 + 944621 = 944820

Showing the first eight; more decompositions exist.
