Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945816, here are decompositions:

5 + 945811 = 945816
7 + 945809 = 945816
17 + 945799 = 945816
29 + 945787 = 945816
83 + 945733 = 945816
139 + 945677 = 945816
227 + 945589 = 945816
229 + 945587 = 945816

Showing the first eight; more decompositions exist.
