Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564516, here are decompositions:

83 + 31564433 = 31564516
353 + 31564163 = 31564516
359 + 31564157 = 31564516
383 + 31564133 = 31564516
563 + 31563953 = 31564516
569 + 31563947 = 31564516
587 + 31563929 = 31564516
617 + 31563899 = 31564516

Showing the first eight; more decompositions exist.
