Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588706, here are decompositions:

7 + 31588699 = 31588706
13 + 31588693 = 31588706
103 + 31588603 = 31588706
223 + 31588483 = 31588706
307 + 31588399 = 31588706
337 + 31588369 = 31588706
349 + 31588357 = 31588706
439 + 31588267 = 31588706

Showing the first eight; more decompositions exist.
