Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488142, here are decompositions:

23 + 488119 = 488142
73 + 488069 = 488142
131 + 488011 = 488142
139 + 488003 = 488142
163 + 487979 = 488142
199 + 487943 = 488142
251 + 487891 = 488142
269 + 487873 = 488142

Showing the first eight; more decompositions exist.
