Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 944780, here are decompositions:

3 + 944777 = 944780
7 + 944773 = 944780
79 + 944701 = 944780
103 + 944677 = 944780
229 + 944551 = 944780
283 + 944497 = 944780
307 + 944473 = 944780
313 + 944467 = 944780

Showing the first eight; more decompositions exist.
