Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583604, here are decompositions:

7 + 31583597 = 31583604
43 + 31583561 = 31583604
83 + 31583521 = 31583604
97 + 31583507 = 31583604
127 + 31583477 = 31583604
167 + 31583437 = 31583604
181 + 31583423 = 31583604
191 + 31583413 = 31583604

Showing the first eight; more decompositions exist.
