Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588676, here are decompositions:

3 + 31588673 = 31588676
19 + 31588657 = 31588676
73 + 31588603 = 31588676
193 + 31588483 = 31588676
277 + 31588399 = 31588676
307 + 31588369 = 31588676
373 + 31588303 = 31588676
409 + 31588267 = 31588676

Showing the first eight; more decompositions exist.
