Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595272, here are decompositions:

29 + 31595243 = 31595272
53 + 31595219 = 31595272
83 + 31595189 = 31595272
131 + 31595141 = 31595272
251 + 31595021 = 31595272
263 + 31595009 = 31595272
281 + 31594991 = 31595272
311 + 31594961 = 31595272

Showing the first eight; more decompositions exist.
