Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627932, here are decompositions:

5 + 31627927 = 31627932
29 + 31627903 = 31627932
43 + 31627889 = 31627932
53 + 31627879 = 31627932
71 + 31627861 = 31627932
131 + 31627801 = 31627932
139 + 31627793 = 31627932
179 + 31627753 = 31627932

Showing the first eight; more decompositions exist.
