Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552698, here are decompositions:

5 + 31552693 = 31552698
17 + 31552681 = 31552698
59 + 31552639 = 31552698
109 + 31552589 = 31552698
211 + 31552487 = 31552698
269 + 31552429 = 31552698
277 + 31552421 = 31552698
311 + 31552387 = 31552698

Showing the first eight; more decompositions exist.
