Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625862, here are decompositions:

13 + 31625849 = 31625862
19 + 31625843 = 31625862
41 + 31625821 = 31625862
43 + 31625819 = 31625862
83 + 31625779 = 31625862
89 + 31625773 = 31625862
101 + 31625761 = 31625862
109 + 31625753 = 31625862

Showing the first eight; more decompositions exist.
