Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523950, here are decompositions:

11 + 31523939 = 31523950
149 + 31523801 = 31523950
197 + 31523753 = 31523950
281 + 31523669 = 31523950
317 + 31523633 = 31523950
509 + 31523441 = 31523950
569 + 31523381 = 31523950
641 + 31523309 = 31523950

Showing the first eight; more decompositions exist.
