Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487948, here are decompositions:

5 + 487943 = 487948
59 + 487889 = 487948
137 + 487811 = 487948
179 + 487769 = 487948
191 + 487757 = 487948
239 + 487709 = 487948
257 + 487691 = 487948
311 + 487637 = 487948

Showing the first eight; more decompositions exist.
