Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481918, here are decompositions:

71 + 481847 = 481918
131 + 481787 = 481918
149 + 481769 = 481918
167 + 481751 = 481918
197 + 481721 = 481918
251 + 481667 = 481918
347 + 481571 = 481918
449 + 481469 = 481918

Showing the first eight; more decompositions exist.
