Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488180, here are decompositions:

19 + 488161 = 488180
31 + 488149 = 488180
37 + 488143 = 488180
61 + 488119 = 488180
283 + 487897 = 488180
307 + 487873 = 488180
337 + 487843 = 488180
349 + 487831 = 488180

Showing the first eight; more decompositions exist.
