Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595504, here are decompositions:

37 + 31595467 = 31595504
97 + 31595407 = 31595504
331 + 31595173 = 31595504
541 + 31594963 = 31595504
601 + 31594903 = 31595504
631 + 31594873 = 31595504
643 + 31594861 = 31595504
691 + 31594813 = 31595504

Showing the first eight; more decompositions exist.
