Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 930820, here are decompositions:

3 + 930817 = 930820
41 + 930779 = 930820
47 + 930773 = 930820
71 + 930749 = 930820
83 + 930737 = 930820
101 + 930719 = 930820
113 + 930707 = 930820
131 + 930689 = 930820

Showing the first eight; more decompositions exist.
