Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583756, here are decompositions:

3 + 31583753 = 31583756
7 + 31583749 = 31583756
97 + 31583659 = 31583756
229 + 31583527 = 31583756
307 + 31583449 = 31583756
433 + 31583323 = 31583756
487 + 31583269 = 31583756
499 + 31583257 = 31583756

Showing the first eight; more decompositions exist.
