Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559014, here are decompositions:

17 + 31558997 = 31559014
41 + 31558973 = 31559014
131 + 31558883 = 31559014
167 + 31558847 = 31559014
191 + 31558823 = 31559014
281 + 31558733 = 31559014
677 + 31558337 = 31559014
761 + 31558253 = 31559014

Showing the first eight; more decompositions exist.
