Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487970, here are decompositions:

37 + 487933 = 487970
73 + 487897 = 487970
79 + 487891 = 487970
97 + 487873 = 487970
127 + 487843 = 487970
139 + 487831 = 487970
151 + 487819 = 487970
181 + 487789 = 487970

Showing the first eight; more decompositions exist.
