Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595558, here are decompositions:

151 + 31595407 = 31595558
307 + 31595251 = 31595558
349 + 31595209 = 31595558
457 + 31595101 = 31595558
499 + 31595059 = 31595558
571 + 31594987 = 31595558
691 + 31594867 = 31595558
751 + 31594807 = 31595558

Showing the first eight; more decompositions exist.
