Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567534, here are decompositions:

23 + 31567511 = 31567534
83 + 31567451 = 31567534
107 + 31567427 = 31567534
137 + 31567397 = 31567534
263 + 31567271 = 31567534
293 + 31567241 = 31567534
443 + 31567091 = 31567534
491 + 31567043 = 31567534

Showing the first eight; more decompositions exist.
