Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449936, here are decompositions:

5 + 31449931 = 31449936
13 + 31449923 = 31449936
83 + 31449853 = 31449936
113 + 31449823 = 31449936
179 + 31449757 = 31449936
197 + 31449739 = 31449936
239 + 31449697 = 31449936
257 + 31449679 = 31449936

Showing the first eight; more decompositions exist.
