Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588636, here are decompositions:

5 + 31588631 = 31588636
29 + 31588607 = 31588636
113 + 31588523 = 31588636
173 + 31588463 = 31588636
197 + 31588439 = 31588636
269 + 31588367 = 31588636
383 + 31588253 = 31588636
389 + 31588247 = 31588636

Showing the first eight; more decompositions exist.
