Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481478, here are decompositions:

31 + 481447 = 481478
61 + 481417 = 481478
181 + 481297 = 481478
229 + 481249 = 481478
271 + 481207 = 481478
307 + 481171 = 481478
331 + 481147 = 481478
337 + 481141 = 481478

Showing the first eight; more decompositions exist.
