Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544724, here are decompositions:

5 + 31544719 = 31544724
7 + 31544717 = 31544724
11 + 31544713 = 31544724
67 + 31544657 = 31544724
137 + 31544587 = 31544724
151 + 31544573 = 31544724
163 + 31544561 = 31544724
173 + 31544551 = 31544724

Showing the first eight; more decompositions exist.
