Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468984, here are decompositions:

17 + 31468967 = 31468984
83 + 31468901 = 31468984
191 + 31468793 = 31468984
227 + 31468757 = 31468984
257 + 31468727 = 31468984
317 + 31468667 = 31468984
347 + 31468637 = 31468984
353 + 31468631 = 31468984

Showing the first eight; more decompositions exist.
