Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500300, here are decompositions:

19 + 31500281 = 31500300
37 + 31500263 = 31500300
79 + 31500221 = 31500300
103 + 31500197 = 31500300
107 + 31500193 = 31500300
113 + 31500187 = 31500300
151 + 31500149 = 31500300
193 + 31500107 = 31500300

Showing the first eight; more decompositions exist.
