Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488988, here are decompositions:

7 + 488981 = 488988
29 + 488959 = 488988
41 + 488947 = 488988
67 + 488921 = 488988
79 + 488909 = 488988
109 + 488879 = 488988
127 + 488861 = 488988
167 + 488821 = 488988

Showing the first eight; more decompositions exist.
