Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594236, here are decompositions:

43 + 31594193 = 31594236
73 + 31594163 = 31594236
103 + 31594133 = 31594236
139 + 31594097 = 31594236
173 + 31594063 = 31594236
197 + 31594039 = 31594236
277 + 31593959 = 31594236
283 + 31593953 = 31594236

Showing the first eight; more decompositions exist.
