Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483136, here are decompositions:

19 + 31483117 = 31483136
43 + 31483093 = 31483136
67 + 31483069 = 31483136
163 + 31482973 = 31483136
229 + 31482907 = 31483136
277 + 31482859 = 31483136
313 + 31482823 = 31483136
337 + 31482799 = 31483136

Showing the first eight; more decompositions exist.
