Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583644, here are decompositions:

3 + 31583641 = 31583644
11 + 31583633 = 31583644
17 + 31583627 = 31583644
23 + 31583621 = 31583644
47 + 31583597 = 31583644
83 + 31583561 = 31583644
137 + 31583507 = 31583644
167 + 31583477 = 31583644

Showing the first eight; more decompositions exist.
