Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594238, here are decompositions:

79 + 31594159 = 31594238
157 + 31594081 = 31594238
199 + 31594039 = 31594238
307 + 31593931 = 31594238
337 + 31593901 = 31594238
607 + 31593631 = 31594238
631 + 31593607 = 31594238
727 + 31593511 = 31594238

Showing the first eight; more decompositions exist.
