Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595758, here are decompositions:

41 + 31595717 = 31595758
71 + 31595687 = 31595758
101 + 31595657 = 31595758
191 + 31595567 = 31595758
479 + 31595279 = 31595758
521 + 31595237 = 31595758
569 + 31595189 = 31595758
617 + 31595141 = 31595758

Showing the first eight; more decompositions exist.
