Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534300, here are decompositions:

3 + 31534297 = 31534300
29 + 31534271 = 31534300
53 + 31534247 = 31534300
59 + 31534241 = 31534300
101 + 31534199 = 31534300
113 + 31534187 = 31534300
131 + 31534169 = 31534300
179 + 31534121 = 31534300

Showing the first eight; more decompositions exist.
