Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487814, here are decompositions:

3 + 487811 = 487814
31 + 487783 = 487814
73 + 487741 = 487814
97 + 487717 = 487814
157 + 487657 = 487814
163 + 487651 = 487814
211 + 487603 = 487814
307 + 487507 = 487814

Showing the first eight; more decompositions exist.
