Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481880, here are decompositions:

13 + 481867 = 481880
19 + 481861 = 481880
31 + 481849 = 481880
37 + 481843 = 481880
43 + 481837 = 481880
67 + 481813 = 481880
73 + 481807 = 481880
79 + 481801 = 481880

Showing the first eight; more decompositions exist.
