Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487748, here are decompositions:

7 + 487741 = 487748
31 + 487717 = 487748
67 + 487681 = 487748
97 + 487651 = 487748
241 + 487507 = 487748
271 + 487477 = 487748
277 + 487471 = 487748
367 + 487381 = 487748

Showing the first eight; more decompositions exist.
