Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583630, here are decompositions:

3 + 31583627 = 31583630
103 + 31583527 = 31583630
109 + 31583521 = 31583630
181 + 31583449 = 31583630
193 + 31583437 = 31583630
277 + 31583353 = 31583630
307 + 31583323 = 31583630
349 + 31583281 = 31583630

Showing the first eight; more decompositions exist.
