Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488104, here are decompositions:

3 + 31488101 = 31488104
13 + 31488091 = 31488104
73 + 31488031 = 31488104
127 + 31487977 = 31488104
163 + 31487941 = 31488104
457 + 31487647 = 31488104
463 + 31487641 = 31488104
523 + 31487581 = 31488104

Showing the first eight; more decompositions exist.
