Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595698, here are decompositions:

11 + 31595687 = 31595698
41 + 31595657 = 31595698
131 + 31595567 = 31595698
311 + 31595387 = 31595698
419 + 31595279 = 31595698
461 + 31595237 = 31595698
479 + 31595219 = 31595698
509 + 31595189 = 31595698

Showing the first eight; more decompositions exist.
