Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487538, here are decompositions:

31 + 487507 = 487538
61 + 487477 = 487538
67 + 487471 = 487538
109 + 487429 = 487538
151 + 487387 = 487538
157 + 487381 = 487538
277 + 487261 = 487538
439 + 487099 = 487538

Showing the first eight; more decompositions exist.
