Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488036, here are decompositions:

5 + 31488031 = 31488036
17 + 31488019 = 31488036
23 + 31488013 = 31488036
43 + 31487993 = 31488036
59 + 31487977 = 31488036
79 + 31487957 = 31488036
163 + 31487873 = 31488036
233 + 31487803 = 31488036

Showing the first eight; more decompositions exist.
