Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484250, here are decompositions:

11 + 31484239 = 31484250
13 + 31484237 = 31484250
41 + 31484209 = 31484250
43 + 31484207 = 31484250
47 + 31484203 = 31484250
71 + 31484179 = 31484250
73 + 31484177 = 31484250
89 + 31484161 = 31484250

Showing the first eight; more decompositions exist.
