Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625910, here are decompositions:

61 + 31625849 = 31625910
67 + 31625843 = 31625910
89 + 31625821 = 31625910
103 + 31625807 = 31625910
131 + 31625779 = 31625910
137 + 31625773 = 31625910
149 + 31625761 = 31625910
157 + 31625753 = 31625910

Showing the first eight; more decompositions exist.
