Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487156, here are decompositions:

23 + 487133 = 487156
83 + 487073 = 487156
107 + 487049 = 487156
149 + 487007 = 487156
179 + 486977 = 487156
227 + 486929 = 487156
233 + 486923 = 487156
317 + 486839 = 487156

Showing the first eight; more decompositions exist.
