Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583462, here are decompositions:

13 + 31583449 = 31583462
109 + 31583353 = 31583462
139 + 31583323 = 31583462
181 + 31583281 = 31583462
193 + 31583269 = 31583462
331 + 31583131 = 31583462
439 + 31583023 = 31583462
571 + 31582891 = 31583462

Showing the first eight; more decompositions exist.
