Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496976, here are decompositions:

13 + 31496963 = 31496976
19 + 31496957 = 31496976
29 + 31496947 = 31496976
59 + 31496917 = 31496976
103 + 31496873 = 31496976
113 + 31496863 = 31496976
149 + 31496827 = 31496976
157 + 31496819 = 31496976

Showing the first eight; more decompositions exist.
