Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514300, here are decompositions:

3 + 31514297 = 31514300
61 + 31514239 = 31514300
79 + 31514221 = 31514300
109 + 31514191 = 31514300
151 + 31514149 = 31514300
157 + 31514143 = 31514300
199 + 31514101 = 31514300
241 + 31514059 = 31514300

Showing the first eight; more decompositions exist.
