Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497448, here are decompositions:

5 + 31497443 = 31497448
89 + 31497359 = 31497448
107 + 31497341 = 31497448
149 + 31497299 = 31497448
197 + 31497251 = 31497448
491 + 31496957 = 31497448
881 + 31496567 = 31497448
911 + 31496537 = 31497448

Showing the first eight; more decompositions exist.
