Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483160, here are decompositions:

43 + 31483117 = 31483160
67 + 31483093 = 31483160
73 + 31483087 = 31483160
109 + 31483051 = 31483160
157 + 31483003 = 31483160
271 + 31482889 = 31483160
337 + 31482823 = 31483160
547 + 31482613 = 31483160

Showing the first eight; more decompositions exist.
