Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487998, here are decompositions:

19 + 487979 = 487998
101 + 487897 = 487998
107 + 487891 = 487998
109 + 487889 = 487998
167 + 487831 = 487998
179 + 487819 = 487998
229 + 487769 = 487998
241 + 487757 = 487998

Showing the first eight; more decompositions exist.
