Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543696, here are decompositions:

5 + 31543691 = 31543696
53 + 31543643 = 31543696
167 + 31543529 = 31543696
347 + 31543349 = 31543696
479 + 31543217 = 31543696
563 + 31543133 = 31543696
593 + 31543103 = 31543696
617 + 31543079 = 31543696

Showing the first eight; more decompositions exist.
