Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595264, here are decompositions:

13 + 31595251 = 31595264
163 + 31595101 = 31595264
277 + 31594987 = 31595264
397 + 31594867 = 31595264
457 + 31594807 = 31595264
691 + 31594573 = 31595264
991 + 31594273 = 31595264
1201 + 31594063 = 31595264

Showing the first eight; more decompositions exist.
