Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487806, here are decompositions:

13 + 487793 = 487806
17 + 487789 = 487806
23 + 487783 = 487806
37 + 487769 = 487806
73 + 487733 = 487806
79 + 487727 = 487806
89 + 487717 = 487806
97 + 487709 = 487806

Showing the first eight; more decompositions exist.
