Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595608, here are decompositions:

41 + 31595567 = 31595608
389 + 31595219 = 31595608
419 + 31595189 = 31595608
431 + 31595177 = 31595608
467 + 31595141 = 31595608
587 + 31595021 = 31595608
599 + 31595009 = 31595608
617 + 31594991 = 31595608

Showing the first eight; more decompositions exist.
