Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482210, here are decompositions:

31 + 31482179 = 31482210
37 + 31482173 = 31482210
41 + 31482169 = 31482210
43 + 31482167 = 31482210
107 + 31482103 = 31482210
113 + 31482097 = 31482210
127 + 31482083 = 31482210
163 + 31482047 = 31482210

Showing the first eight; more decompositions exist.
