Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501664, here are decompositions:

3 + 31501661 = 31501664
31 + 31501633 = 31501664
43 + 31501621 = 31501664
97 + 31501567 = 31501664
127 + 31501537 = 31501664
277 + 31501387 = 31501664
331 + 31501333 = 31501664
433 + 31501231 = 31501664

Showing the first eight; more decompositions exist.
