Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484016, here are decompositions:

37 + 31483979 = 31484016
59 + 31483957 = 31484016
89 + 31483927 = 31484016
97 + 31483919 = 31484016
103 + 31483913 = 31484016
127 + 31483889 = 31484016
139 + 31483877 = 31484016
197 + 31483819 = 31484016

Showing the first eight; more decompositions exist.
