Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496962, here are decompositions:

5 + 31496957 = 31496962
41 + 31496921 = 31496962
89 + 31496873 = 31496962
179 + 31496783 = 31496962
269 + 31496693 = 31496962
293 + 31496669 = 31496962
389 + 31496573 = 31496962
443 + 31496519 = 31496962

Showing the first eight; more decompositions exist.
