Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594892, here are decompositions:

19 + 31594873 = 31594892
31 + 31594861 = 31594892
79 + 31594813 = 31594892
163 + 31594729 = 31594892
193 + 31594699 = 31594892
211 + 31594681 = 31594892
283 + 31594609 = 31594892
313 + 31594579 = 31594892

Showing the first eight; more decompositions exist.
