Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469880, here are decompositions:

3 + 469877 = 469880
31 + 469849 = 469880
79 + 469801 = 469880
127 + 469753 = 469880
157 + 469723 = 469880
163 + 469717 = 469880
193 + 469687 = 469880
223 + 469657 = 469880

Showing the first eight; more decompositions exist.
