Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583534, here are decompositions:

7 + 31583527 = 31583534
13 + 31583521 = 31583534
97 + 31583437 = 31583534
181 + 31583353 = 31583534
211 + 31583323 = 31583534
277 + 31583257 = 31583534
397 + 31583137 = 31583534
487 + 31583047 = 31583534

Showing the first eight; more decompositions exist.
