Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503996, here are decompositions:

19 + 31503977 = 31503996
23 + 31503973 = 31503996
67 + 31503929 = 31503996
79 + 31503917 = 31503996
109 + 31503887 = 31503996
113 + 31503883 = 31503996
149 + 31503847 = 31503996
197 + 31503799 = 31503996

Showing the first eight; more decompositions exist.
