Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487892, here are decompositions:

3 + 487889 = 487892
19 + 487873 = 487892
61 + 487831 = 487892
73 + 487819 = 487892
103 + 487789 = 487892
109 + 487783 = 487892
151 + 487741 = 487892
211 + 487681 = 487892

Showing the first eight; more decompositions exist.
