Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516726, here are decompositions:

23 + 31516703 = 31516726
29 + 31516697 = 31516726
107 + 31516619 = 31516726
113 + 31516613 = 31516726
167 + 31516559 = 31516726
233 + 31516493 = 31516726
257 + 31516469 = 31516726
347 + 31516379 = 31516726

Showing the first eight; more decompositions exist.
