Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482262, here are decompositions:

5 + 31482257 = 31482262
83 + 31482179 = 31482262
89 + 31482173 = 31482262
173 + 31482089 = 31482262
179 + 31482083 = 31482262
281 + 31481981 = 31482262
311 + 31481951 = 31482262
419 + 31481843 = 31482262

Showing the first eight; more decompositions exist.
