Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627824, here are decompositions:

13 + 31627811 = 31627824
23 + 31627801 = 31627824
31 + 31627793 = 31627824
61 + 31627763 = 31627824
71 + 31627753 = 31627824
73 + 31627751 = 31627824
97 + 31627727 = 31627824
103 + 31627721 = 31627824

Showing the first eight; more decompositions exist.
