Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595498, here are decompositions:

31 + 31595467 = 31595498
127 + 31595371 = 31595498
397 + 31595101 = 31595498
439 + 31595059 = 31595498
499 + 31594999 = 31595498
631 + 31594867 = 31595498
691 + 31594807 = 31595498
751 + 31594747 = 31595498

Showing the first eight; more decompositions exist.
