Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583764, here are decompositions:

11 + 31583753 = 31583764
71 + 31583693 = 31583764
101 + 31583663 = 31583764
131 + 31583633 = 31583764
137 + 31583627 = 31583764
167 + 31583597 = 31583764
257 + 31583507 = 31583764
593 + 31583171 = 31583764

Showing the first eight; more decompositions exist.
