Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583998, here are decompositions:

101 + 31583897 = 31583998
167 + 31583831 = 31583998
179 + 31583819 = 31583998
227 + 31583771 = 31583998
269 + 31583729 = 31583998
311 + 31583687 = 31583998
401 + 31583597 = 31583998
449 + 31583549 = 31583998

Showing the first eight; more decompositions exist.
