Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 930780, here are decompositions:

7 + 930773 = 930780
17 + 930763 = 930780
31 + 930749 = 930780
43 + 930737 = 930780
61 + 930719 = 930780
73 + 930707 = 930780
113 + 930667 = 930780
127 + 930653 = 930780

Showing the first eight; more decompositions exist.
