Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484252, here are decompositions:

13 + 31484239 = 31484252
43 + 31484209 = 31484252
73 + 31484179 = 31484252
109 + 31484143 = 31484252
181 + 31484071 = 31484252
193 + 31484059 = 31484252
271 + 31483981 = 31484252
433 + 31483819 = 31484252

Showing the first eight; more decompositions exist.
