Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516964, here are decompositions:

13 + 31516951 = 31516964
211 + 31516753 = 31516964
331 + 31516633 = 31516964
337 + 31516627 = 31516964
397 + 31516567 = 31516964
421 + 31516543 = 31516964
463 + 31516501 = 31516964
541 + 31516423 = 31516964

Showing the first eight; more decompositions exist.
