Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484246, here are decompositions:

7 + 31484239 = 31484246
37 + 31484209 = 31484246
43 + 31484203 = 31484246
67 + 31484179 = 31484246
103 + 31484143 = 31484246
439 + 31483807 = 31484246
457 + 31483789 = 31484246
487 + 31483759 = 31484246

Showing the first eight; more decompositions exist.
