Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594946, here are decompositions:

43 + 31594903 = 31594946
73 + 31594873 = 31594946
79 + 31594867 = 31594946
139 + 31594807 = 31594946
199 + 31594747 = 31594946
337 + 31594609 = 31594946
349 + 31594597 = 31594946
367 + 31594579 = 31594946

Showing the first eight; more decompositions exist.
