Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488140, here are decompositions:

71 + 488069 = 488140
83 + 488057 = 488140
89 + 488051 = 488140
131 + 488009 = 488140
137 + 488003 = 488140
167 + 487973 = 488140
197 + 487943 = 488140
251 + 487889 = 488140

Showing the first eight; more decompositions exist.
