Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487936, here are decompositions:

3 + 487933 = 487936
47 + 487889 = 487936
107 + 487829 = 487936
167 + 487769 = 487936
179 + 487757 = 487936
227 + 487709 = 487936
233 + 487703 = 487936
347 + 487589 = 487936

Showing the first eight; more decompositions exist.
