Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583562, here are decompositions:

13 + 31583549 = 31583562
41 + 31583521 = 31583562
53 + 31583509 = 31583562
113 + 31583449 = 31583562
139 + 31583423 = 31583562
149 + 31583413 = 31583562
211 + 31583351 = 31583562
239 + 31583323 = 31583562

Showing the first eight; more decompositions exist.
