Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482996, here are decompositions:

5 + 31482991 = 31482996
19 + 31482977 = 31482996
23 + 31482973 = 31482996
89 + 31482907 = 31482996
107 + 31482889 = 31482996
137 + 31482859 = 31482996
157 + 31482839 = 31482996
163 + 31482833 = 31482996

Showing the first eight; more decompositions exist.
