Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559462, here are decompositions:

19 + 31559443 = 31559462
61 + 31559401 = 31559462
79 + 31559383 = 31559462
199 + 31559263 = 31559462
211 + 31559251 = 31559462
223 + 31559239 = 31559462
313 + 31559149 = 31559462
331 + 31559131 = 31559462

Showing the first eight; more decompositions exist.
