Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594998, here are decompositions:

7 + 31594991 = 31594998
11 + 31594987 = 31594998
37 + 31594961 = 31594998
67 + 31594931 = 31594998
79 + 31594919 = 31594998
131 + 31594867 = 31594998
137 + 31594861 = 31594998
191 + 31594807 = 31594998

Showing the first eight; more decompositions exist.
