Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484154, here are decompositions:

11 + 31484143 = 31484154
61 + 31484093 = 31484154
73 + 31484081 = 31484154
83 + 31484071 = 31484154
173 + 31483981 = 31484154
197 + 31483957 = 31484154
227 + 31483927 = 31484154
241 + 31483913 = 31484154

Showing the first eight; more decompositions exist.
