Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595242, here are decompositions:

5 + 31595237 = 31595242
23 + 31595219 = 31595242
53 + 31595189 = 31595242
101 + 31595141 = 31595242
179 + 31595063 = 31595242
233 + 31595009 = 31595242
251 + 31594991 = 31595242
281 + 31594961 = 31595242

Showing the first eight; more decompositions exist.
