Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583366, here are decompositions:

13 + 31583353 = 31583366
43 + 31583323 = 31583366
97 + 31583269 = 31583366
109 + 31583257 = 31583366
229 + 31583137 = 31583366
547 + 31582819 = 31583366
733 + 31582633 = 31583366
739 + 31582627 = 31583366

Showing the first eight; more decompositions exist.
