Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488116, here are decompositions:

7 + 31488109 = 31488116
97 + 31488019 = 31488116
103 + 31488013 = 31488116
139 + 31487977 = 31488116
199 + 31487917 = 31488116
313 + 31487803 = 31488116
337 + 31487779 = 31488116
577 + 31487539 = 31488116

Showing the first eight; more decompositions exist.
