Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588606, here are decompositions:

3 + 31588603 = 31588606
83 + 31588523 = 31588606
113 + 31588493 = 31588606
167 + 31588439 = 31588606
239 + 31588367 = 31588606
293 + 31588313 = 31588606
353 + 31588253 = 31588606
359 + 31588247 = 31588606

Showing the first eight; more decompositions exist.
