Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595098, here are decompositions:

89 + 31595009 = 31595098
107 + 31594991 = 31595098
137 + 31594961 = 31595098
167 + 31594931 = 31595098
179 + 31594919 = 31595098
191 + 31594907 = 31595098
677 + 31594421 = 31595098
827 + 31594271 = 31595098

Showing the first eight; more decompositions exist.
