Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537958, here are decompositions:

19 + 31537939 = 31537958
37 + 31537921 = 31537958
97 + 31537861 = 31537958
211 + 31537747 = 31537958
241 + 31537717 = 31537958
271 + 31537687 = 31537958
349 + 31537609 = 31537958
367 + 31537591 = 31537958

Showing the first eight; more decompositions exist.
