Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482200, here are decompositions:

31 + 31482169 = 31482200
97 + 31482103 = 31482200
103 + 31482097 = 31482200
157 + 31482043 = 31482200
163 + 31482037 = 31482200
313 + 31481887 = 31482200
349 + 31481851 = 31482200
433 + 31481767 = 31482200

Showing the first eight; more decompositions exist.
