Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598272, here are decompositions:

5 + 31598267 = 31598272
11 + 31598261 = 31598272
59 + 31598213 = 31598272
71 + 31598201 = 31598272
131 + 31598141 = 31598272
239 + 31598033 = 31598272
263 + 31598009 = 31598272
311 + 31597961 = 31598272

Showing the first eight; more decompositions exist.
