Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482466, here are decompositions:

173 + 31482293 = 31482466
293 + 31482173 = 31482466
347 + 31482119 = 31482466
383 + 31482083 = 31482466
419 + 31482047 = 31482466
599 + 31481867 = 31482466
647 + 31481819 = 31482466
857 + 31481609 = 31482466

Showing the first eight; more decompositions exist.
