Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495036, here are decompositions:

17 + 31495019 = 31495036
113 + 31494923 = 31495036
149 + 31494887 = 31495036
227 + 31494809 = 31495036
269 + 31494767 = 31495036
347 + 31494689 = 31495036
557 + 31494479 = 31495036
569 + 31494467 = 31495036

Showing the first eight; more decompositions exist.
