Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487880, here are decompositions:

7 + 487873 = 487880
37 + 487843 = 487880
61 + 487819 = 487880
97 + 487783 = 487880
139 + 487741 = 487880
163 + 487717 = 487880
199 + 487681 = 487880
223 + 487657 = 487880

Showing the first eight; more decompositions exist.
