Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496896, here are decompositions:

23 + 31496873 = 31496896
113 + 31496783 = 31496896
227 + 31496669 = 31496896
359 + 31496537 = 31496896
467 + 31496429 = 31496896
479 + 31496417 = 31496896
677 + 31496219 = 31496896
773 + 31496123 = 31496896

Showing the first eight; more decompositions exist.
