Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 946816, here are decompositions:

47 + 946769 = 946816
83 + 946733 = 946816
89 + 946727 = 946816
149 + 946667 = 946816
347 + 946469 = 946816
419 + 946397 = 946816
449 + 946367 = 946816
509 + 946307 = 946816

Showing the first eight; more decompositions exist.
