Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488928, here are decompositions:

7 + 488921 = 488928
19 + 488909 = 488928
31 + 488897 = 488928
67 + 488861 = 488928
101 + 488827 = 488928
107 + 488821 = 488928
131 + 488797 = 488928
137 + 488791 = 488928

Showing the first eight; more decompositions exist.
