Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583510, here are decompositions:

3 + 31583507 = 31583510
61 + 31583449 = 31583510
73 + 31583437 = 31583510
97 + 31583413 = 31583510
157 + 31583353 = 31583510
229 + 31583281 = 31583510
241 + 31583269 = 31583510
373 + 31583137 = 31583510

Showing the first eight; more decompositions exist.
