Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469784, here are decompositions:

31 + 469753 = 469784
37 + 469747 = 469784
61 + 469723 = 469784
67 + 469717 = 469784
97 + 469687 = 469784
127 + 469657 = 469784
157 + 469627 = 469784
223 + 469561 = 469784

Showing the first eight; more decompositions exist.
