Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544200, here are decompositions:

11 + 31544189 = 31544200
29 + 31544171 = 31544200
47 + 31544153 = 31544200
101 + 31544099 = 31544200
167 + 31544033 = 31544200
179 + 31544021 = 31544200
239 + 31543961 = 31544200
293 + 31543907 = 31544200

Showing the first eight; more decompositions exist.
