Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 949820, here are decompositions:

31 + 949789 = 949820
43 + 949777 = 949820
61 + 949759 = 949820
199 + 949621 = 949820
211 + 949609 = 949820
307 + 949513 = 949820
349 + 949471 = 949820
367 + 949453 = 949820

Showing the first eight; more decompositions exist.
