Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484198, here are decompositions:

19 + 31484179 = 31484198
37 + 31484161 = 31484198
127 + 31484071 = 31484198
139 + 31484059 = 31484198
241 + 31483957 = 31484198
271 + 31483927 = 31484198
337 + 31483861 = 31484198
379 + 31483819 = 31484198

Showing the first eight; more decompositions exist.
