Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559282, here are decompositions:

19 + 31559263 = 31559282
31 + 31559251 = 31559282
43 + 31559239 = 31559282
151 + 31559131 = 31559282
211 + 31559071 = 31559282
439 + 31558843 = 31559282
463 + 31558819 = 31559282
523 + 31558759 = 31559282

Showing the first eight; more decompositions exist.
