Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535698, here are decompositions:

17 + 31535681 = 31535698
41 + 31535657 = 31535698
59 + 31535639 = 31535698
107 + 31535591 = 31535698
149 + 31535549 = 31535698
269 + 31535429 = 31535698
281 + 31535417 = 31535698
317 + 31535381 = 31535698

Showing the first eight; more decompositions exist.
