Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588616, here are decompositions:

13 + 31588603 = 31588616
313 + 31588303 = 31588616
349 + 31588267 = 31588616
487 + 31588129 = 31588616
613 + 31588003 = 31588616
673 + 31587943 = 31588616
739 + 31587877 = 31588616
757 + 31587859 = 31588616

Showing the first eight; more decompositions exist.
