Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625858, here are decompositions:

37 + 31625821 = 31625858
79 + 31625779 = 31625858
97 + 31625761 = 31625858
127 + 31625731 = 31625858
211 + 31625647 = 31625858
241 + 31625617 = 31625858
349 + 31625509 = 31625858
457 + 31625401 = 31625858

Showing the first eight; more decompositions exist.
