Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625832, here are decompositions:

11 + 31625821 = 31625832
13 + 31625819 = 31625832
53 + 31625779 = 31625832
59 + 31625773 = 31625832
71 + 31625761 = 31625832
79 + 31625753 = 31625832
101 + 31625731 = 31625832
109 + 31625723 = 31625832

Showing the first eight; more decompositions exist.
