Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496566, here are decompositions:

29 + 31496537 = 31496566
47 + 31496519 = 31496566
137 + 31496429 = 31496566
149 + 31496417 = 31496566
197 + 31496369 = 31496566
347 + 31496219 = 31496566
443 + 31496123 = 31496566
467 + 31496099 = 31496566

Showing the first eight; more decompositions exist.
