Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627964, here are decompositions:

3 + 31627961 = 31627964
37 + 31627927 = 31627964
61 + 31627903 = 31627964
103 + 31627861 = 31627964
163 + 31627801 = 31627964
211 + 31627753 = 31627964
337 + 31627627 = 31627964
397 + 31627567 = 31627964

Showing the first eight; more decompositions exist.
