Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463200, here are decompositions:

3 + 31463197 = 31463200
53 + 31463147 = 31463200
101 + 31463099 = 31463200
113 + 31463087 = 31463200
137 + 31463063 = 31463200
269 + 31462931 = 31463200
311 + 31462889 = 31463200
389 + 31462811 = 31463200

Showing the first eight; more decompositions exist.
