Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496938, here are decompositions:

17 + 31496921 = 31496938
197 + 31496741 = 31496938
269 + 31496669 = 31496938
401 + 31496537 = 31496938
419 + 31496519 = 31496938
449 + 31496489 = 31496938
509 + 31496429 = 31496938
521 + 31496417 = 31496938

Showing the first eight; more decompositions exist.
