Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483172, here are decompositions:

3 + 31483169 = 31483172
79 + 31483093 = 31483172
103 + 31483069 = 31483172
181 + 31482991 = 31483172
199 + 31482973 = 31483172
283 + 31482889 = 31483172
313 + 31482859 = 31483172
349 + 31482823 = 31483172

Showing the first eight; more decompositions exist.
