Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532698, here are decompositions:

5 + 31532693 = 31532698
11 + 31532687 = 31532698
59 + 31532639 = 31532698
101 + 31532597 = 31532698
191 + 31532507 = 31532698
269 + 31532429 = 31532698
359 + 31532339 = 31532698
419 + 31532279 = 31532698

Showing the first eight; more decompositions exist.
