Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503896, here are decompositions:

13 + 31503883 = 31503896
43 + 31503853 = 31503896
97 + 31503799 = 31503896
163 + 31503733 = 31503896
223 + 31503673 = 31503896
337 + 31503559 = 31503896
367 + 31503529 = 31503896
757 + 31503139 = 31503896

Showing the first eight; more decompositions exist.
