Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482474, here are decompositions:

47 + 31482427 = 31482474
73 + 31482401 = 31482474
131 + 31482343 = 31482474
137 + 31482337 = 31482474
167 + 31482307 = 31482474
181 + 31482293 = 31482474
193 + 31482281 = 31482474
197 + 31482277 = 31482474

Showing the first eight; more decompositions exist.
