Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534984, here are decompositions:

3 + 31534981 = 31534984
23 + 31534961 = 31534984
71 + 31534913 = 31534984
113 + 31534871 = 31534984
197 + 31534787 = 31534984
227 + 31534757 = 31534984
233 + 31534751 = 31534984
293 + 31534691 = 31534984

Showing the first eight; more decompositions exist.
