Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576232, here are decompositions:

13 + 31576219 = 31576232
31 + 31576201 = 31576232
223 + 31576009 = 31576232
229 + 31576003 = 31576232
241 + 31575991 = 31576232
409 + 31575823 = 31576232
433 + 31575799 = 31576232
439 + 31575793 = 31576232

Showing the first eight; more decompositions exist.
