Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482550, here are decompositions:

41 + 31482509 = 31482550
149 + 31482401 = 31482550
257 + 31482293 = 31482550
269 + 31482281 = 31482550
293 + 31482257 = 31482550
383 + 31482167 = 31482550
431 + 31482119 = 31482550
461 + 31482089 = 31482550

Showing the first eight; more decompositions exist.
