Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480696, here are decompositions:

3 + 31480693 = 31480696
47 + 31480649 = 31480696
167 + 31480529 = 31480696
263 + 31480433 = 31480696
347 + 31480349 = 31480696
593 + 31480103 = 31480696
617 + 31480079 = 31480696
647 + 31480049 = 31480696

Showing the first eight; more decompositions exist.
