Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588914, here are decompositions:

17 + 31588897 = 31588914
67 + 31588847 = 31588914
101 + 31588813 = 31588914
107 + 31588807 = 31588914
241 + 31588673 = 31588914
257 + 31588657 = 31588914
271 + 31588643 = 31588914
283 + 31588631 = 31588914

Showing the first eight; more decompositions exist.
