Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 946820, here are decompositions:

19 + 946801 = 946820
37 + 946783 = 946820
67 + 946753 = 946820
79 + 946741 = 946820
103 + 946717 = 946820
139 + 946681 = 946820
151 + 946669 = 946820
157 + 946663 = 946820

Showing the first eight; more decompositions exist.
