Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594964, here are decompositions:

3 + 31594961 = 31594964
61 + 31594903 = 31594964
97 + 31594867 = 31594964
103 + 31594861 = 31594964
151 + 31594813 = 31594964
157 + 31594807 = 31594964
283 + 31594681 = 31594964
337 + 31594627 = 31594964

Showing the first eight; more decompositions exist.
