Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482340, here are decompositions:

3 + 31482337 = 31482340
47 + 31482293 = 31482340
59 + 31482281 = 31482340
83 + 31482257 = 31482340
167 + 31482173 = 31482340
173 + 31482167 = 31482340
251 + 31482089 = 31482340
257 + 31482083 = 31482340

Showing the first eight; more decompositions exist.
