Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484084, here are decompositions:

3 + 31484081 = 31484084
13 + 31484071 = 31484084
103 + 31483981 = 31484084
127 + 31483957 = 31484084
157 + 31483927 = 31484084
223 + 31483861 = 31484084
277 + 31483807 = 31484084
283 + 31483801 = 31484084

Showing the first eight; more decompositions exist.
