Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487836, here are decompositions:

5 + 487831 = 487836
7 + 487829 = 487836
17 + 487819 = 487836
43 + 487793 = 487836
47 + 487789 = 487836
53 + 487783 = 487836
67 + 487769 = 487836
79 + 487757 = 487836

Showing the first eight; more decompositions exist.
