Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497496, here are decompositions:

5 + 31497491 = 31497496
29 + 31497467 = 31497496
47 + 31497449 = 31497496
53 + 31497443 = 31497496
137 + 31497359 = 31497496
197 + 31497299 = 31497496
677 + 31496819 = 31497496
827 + 31496669 = 31497496

Showing the first eight; more decompositions exist.
