Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488072, here are decompositions:

3 + 488069 = 488072
61 + 488011 = 488072
139 + 487933 = 488072
181 + 487891 = 488072
199 + 487873 = 488072
229 + 487843 = 488072
241 + 487831 = 488072
283 + 487789 = 488072

Showing the first eight; more decompositions exist.
