Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488056, here are decompositions:

3 + 31488053 = 31488056
37 + 31488019 = 31488056
43 + 31488013 = 31488056
79 + 31487977 = 31488056
139 + 31487917 = 31488056
277 + 31487779 = 31488056
409 + 31487647 = 31488056
709 + 31487347 = 31488056

Showing the first eight; more decompositions exist.
