Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594838, here are decompositions:

31 + 31594807 = 31594838
109 + 31594729 = 31594838
139 + 31594699 = 31594838
157 + 31594681 = 31594838
211 + 31594627 = 31594838
229 + 31594609 = 31594838
241 + 31594597 = 31594838
337 + 31594501 = 31594838

Showing the first eight; more decompositions exist.
