Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594742, here are decompositions:

13 + 31594729 = 31594742
43 + 31594699 = 31594742
61 + 31594681 = 31594742
163 + 31594579 = 31594742
241 + 31594501 = 31594742
313 + 31594429 = 31594742
349 + 31594393 = 31594742
409 + 31594333 = 31594742

Showing the first eight; more decompositions exist.
