Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590698, here are decompositions:

31 + 31590667 = 31590698
67 + 31590631 = 31590698
109 + 31590589 = 31590698
127 + 31590571 = 31590698
199 + 31590499 = 31590698
211 + 31590487 = 31590698
229 + 31590469 = 31590698
277 + 31590421 = 31590698

Showing the first eight; more decompositions exist.
