Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594932, here are decompositions:

13 + 31594919 = 31594932
29 + 31594903 = 31594932
59 + 31594873 = 31594932
71 + 31594861 = 31594932
163 + 31594769 = 31594932
233 + 31594699 = 31594932
241 + 31594691 = 31594932
251 + 31594681 = 31594932

Showing the first eight; more decompositions exist.
