Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583974, here are decompositions:

3 + 31583971 = 31583974
53 + 31583921 = 31583974
137 + 31583837 = 31583974
197 + 31583777 = 31583974
281 + 31583693 = 31583974
311 + 31583663 = 31583974
347 + 31583627 = 31583974
353 + 31583621 = 31583974

Showing the first eight; more decompositions exist.
