Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594814, here are decompositions:

3 + 31594811 = 31594814
7 + 31594807 = 31594814
67 + 31594747 = 31594814
241 + 31594573 = 31594814
313 + 31594501 = 31594814
421 + 31594393 = 31594814
463 + 31594351 = 31594814
541 + 31594273 = 31594814

Showing the first eight; more decompositions exist.
