Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588654, here are decompositions:

11 + 31588643 = 31588654
23 + 31588631 = 31588654
47 + 31588607 = 31588654
131 + 31588523 = 31588654
191 + 31588463 = 31588654
347 + 31588307 = 31588654
401 + 31588253 = 31588654
593 + 31588061 = 31588654

Showing the first eight; more decompositions exist.
