Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547698, here are decompositions:

5 + 31547693 = 31547698
89 + 31547609 = 31547698
107 + 31547591 = 31547698
167 + 31547531 = 31547698
179 + 31547519 = 31547698
191 + 31547507 = 31547698
227 + 31547471 = 31547698
239 + 31547459 = 31547698

Showing the first eight; more decompositions exist.
