Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583996, here are decompositions:

7 + 31583989 = 31583996
13 + 31583983 = 31583996
139 + 31583857 = 31583996
193 + 31583803 = 31583996
337 + 31583659 = 31583996
487 + 31583509 = 31583996
547 + 31583449 = 31583996
643 + 31583353 = 31583996

Showing the first eight; more decompositions exist.
