Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484168, here are decompositions:

7 + 31484161 = 31484168
97 + 31484071 = 31484168
109 + 31484059 = 31484168
211 + 31483957 = 31484168
241 + 31483927 = 31484168
307 + 31483861 = 31484168
349 + 31483819 = 31484168
367 + 31483801 = 31484168

Showing the first eight; more decompositions exist.
