Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600272, here are decompositions:

13 + 31600259 = 31600272
71 + 31600201 = 31600272
79 + 31600193 = 31600272
83 + 31600189 = 31600272
139 + 31600133 = 31600272
173 + 31600099 = 31600272
211 + 31600061 = 31600272
229 + 31600043 = 31600272

Showing the first eight; more decompositions exist.
