Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594136, here are decompositions:

3 + 31594133 = 31594136
73 + 31594063 = 31594136
97 + 31594039 = 31594136
193 + 31593943 = 31594136
199 + 31593937 = 31594136
349 + 31593787 = 31594136
373 + 31593763 = 31594136
433 + 31593703 = 31594136

Showing the first eight; more decompositions exist.
