Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496936, here are decompositions:

19 + 31496917 = 31496936
73 + 31496863 = 31496936
109 + 31496827 = 31496936
127 + 31496809 = 31496936
157 + 31496779 = 31496936
337 + 31496599 = 31496936
349 + 31496587 = 31496936
397 + 31496539 = 31496936

Showing the first eight; more decompositions exist.
