Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518996, here are decompositions:

7 + 31518989 = 31518996
43 + 31518953 = 31518996
73 + 31518923 = 31518996
83 + 31518913 = 31518996
97 + 31518899 = 31518996
127 + 31518869 = 31518996
137 + 31518859 = 31518996
239 + 31518757 = 31518996

Showing the first eight; more decompositions exist.
