Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523944, here are decompositions:

3 + 31523941 = 31523944
5 + 31523939 = 31523944
191 + 31523753 = 31523944
293 + 31523651 = 31523944
311 + 31523633 = 31523944
467 + 31523477 = 31523944
503 + 31523441 = 31523944
563 + 31523381 = 31523944

Showing the first eight; more decompositions exist.
