Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625944, here are decompositions:

5 + 31625939 = 31625944
101 + 31625843 = 31625944
137 + 31625807 = 31625944
167 + 31625777 = 31625944
191 + 31625753 = 31625944
263 + 31625681 = 31625944
293 + 31625651 = 31625944
491 + 31625453 = 31625944

Showing the first eight; more decompositions exist.
