Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483202, here are decompositions:

109 + 31483093 = 31483202
151 + 31483051 = 31483202
199 + 31483003 = 31483202
211 + 31482991 = 31483202
229 + 31482973 = 31483202
313 + 31482889 = 31483202
379 + 31482823 = 31483202
571 + 31482631 = 31483202

Showing the first eight; more decompositions exist.
