Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589698, here are decompositions:

5 + 31589693 = 31589698
131 + 31589567 = 31589698
137 + 31589561 = 31589698
359 + 31589339 = 31589698
401 + 31589297 = 31589698
599 + 31589099 = 31589698
641 + 31589057 = 31589698
719 + 31588979 = 31589698

Showing the first eight; more decompositions exist.
