Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627984, here are decompositions:

5 + 31627979 = 31627984
23 + 31627961 = 31627984
53 + 31627931 = 31627984
173 + 31627811 = 31627984
191 + 31627793 = 31627984
233 + 31627751 = 31627984
257 + 31627727 = 31627984
263 + 31627721 = 31627984

Showing the first eight; more decompositions exist.
