Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458204, here are decompositions:

7 + 31458197 = 31458204
13 + 31458191 = 31458204
17 + 31458187 = 31458204
31 + 31458173 = 31458204
73 + 31458131 = 31458204
191 + 31458013 = 31458204
293 + 31457911 = 31458204
347 + 31457857 = 31458204

Showing the first eight; more decompositions exist.
