Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583770, here are decompositions:

17 + 31583753 = 31583770
41 + 31583729 = 31583770
83 + 31583687 = 31583770
107 + 31583663 = 31583770
137 + 31583633 = 31583770
149 + 31583621 = 31583770
173 + 31583597 = 31583770
263 + 31583507 = 31583770

Showing the first eight; more decompositions exist.
