Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588684, here are decompositions:

5 + 31588679 = 31588684
11 + 31588673 = 31588684
41 + 31588643 = 31588684
53 + 31588631 = 31588684
191 + 31588493 = 31588684
317 + 31588367 = 31588684
353 + 31588331 = 31588684
431 + 31588253 = 31588684

Showing the first eight; more decompositions exist.
