Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560462, here are decompositions:

29 + 31560433 = 31560462
61 + 31560401 = 31560462
71 + 31560391 = 31560462
79 + 31560383 = 31560462
163 + 31560299 = 31560462
211 + 31560251 = 31560462
223 + 31560239 = 31560462
229 + 31560233 = 31560462

Showing the first eight; more decompositions exist.
