Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588608, here are decompositions:

5 + 31588603 = 31588608
47 + 31588561 = 31588608
137 + 31588471 = 31588608
167 + 31588441 = 31588608
239 + 31588369 = 31588608
241 + 31588367 = 31588608
251 + 31588357 = 31588608
257 + 31588351 = 31588608

Showing the first eight; more decompositions exist.
