Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484868, here are decompositions:

5 + 31484863 = 31484868
29 + 31484839 = 31484868
31 + 31484837 = 31484868
47 + 31484821 = 31484868
67 + 31484801 = 31484868
71 + 31484797 = 31484868
97 + 31484771 = 31484868
127 + 31484741 = 31484868

Showing the first eight; more decompositions exist.
