Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594908, here are decompositions:

5 + 31594903 = 31594908
31 + 31594877 = 31594908
41 + 31594867 = 31594908
47 + 31594861 = 31594908
97 + 31594811 = 31594908
101 + 31594807 = 31594908
109 + 31594799 = 31594908
139 + 31594769 = 31594908

Showing the first eight; more decompositions exist.
