Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488512, here are decompositions:

53 + 488459 = 488512
71 + 488441 = 488512
113 + 488399 = 488512
131 + 488381 = 488512
173 + 488339 = 488512
179 + 488333 = 488512
191 + 488321 = 488512
251 + 488261 = 488512

Showing the first eight; more decompositions exist.
