Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487926, here are decompositions:

29 + 487897 = 487926
37 + 487889 = 487926
53 + 487873 = 487926
83 + 487843 = 487926
97 + 487829 = 487926
107 + 487819 = 487926
137 + 487789 = 487926
157 + 487769 = 487926

Showing the first eight; more decompositions exist.
