Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583992, here are decompositions:

3 + 31583989 = 31583992
71 + 31583921 = 31583992
173 + 31583819 = 31583992
239 + 31583753 = 31583992
263 + 31583729 = 31583992
359 + 31583633 = 31583992
431 + 31583561 = 31583992
443 + 31583549 = 31583992

Showing the first eight; more decompositions exist.
