Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594406, here are decompositions:

7 + 31594399 = 31594406
13 + 31594393 = 31594406
73 + 31594333 = 31594406
97 + 31594309 = 31594406
367 + 31594039 = 31594406
463 + 31593943 = 31594406
619 + 31593787 = 31594406
643 + 31593763 = 31594406

Showing the first eight; more decompositions exist.
