Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583932, here are decompositions:

11 + 31583921 = 31583932
101 + 31583831 = 31583932
113 + 31583819 = 31583932
179 + 31583753 = 31583932
239 + 31583693 = 31583932
269 + 31583663 = 31583932
311 + 31583621 = 31583932
383 + 31583549 = 31583932

Showing the first eight; more decompositions exist.
