Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608300, here are decompositions:

29 + 31608271 = 31608300
37 + 31608263 = 31608300
83 + 31608217 = 31608300
131 + 31608169 = 31608300
137 + 31608163 = 31608300
151 + 31608149 = 31608300
167 + 31608133 = 31608300
193 + 31608107 = 31608300

Showing the first eight; more decompositions exist.
