Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594956, here are decompositions:

37 + 31594919 = 31594956
53 + 31594903 = 31594956
73 + 31594883 = 31594956
79 + 31594877 = 31594956
83 + 31594873 = 31594956
89 + 31594867 = 31594956
149 + 31594807 = 31594956
157 + 31594799 = 31594956

Showing the first eight; more decompositions exist.
