Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488128, here are decompositions:

59 + 488069 = 488128
71 + 488057 = 488128
107 + 488021 = 488128
131 + 487997 = 488128
149 + 487979 = 488128
239 + 487889 = 488128
317 + 487811 = 488128
359 + 487769 = 488128

Showing the first eight; more decompositions exist.
