Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595468, here are decompositions:

61 + 31595407 = 31595468
97 + 31595371 = 31595468
367 + 31595101 = 31595468
409 + 31595059 = 31595468
601 + 31594867 = 31595468
607 + 31594861 = 31595468
661 + 31594807 = 31595468
739 + 31594729 = 31595468

Showing the first eight; more decompositions exist.
