Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488900, here are decompositions:

3 + 488897 = 488900
7 + 488893 = 488900
67 + 488833 = 488900
73 + 488827 = 488900
79 + 488821 = 488900
103 + 488797 = 488900
109 + 488791 = 488900
151 + 488749 = 488900

Showing the first eight; more decompositions exist.
