Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487974, here are decompositions:

31 + 487943 = 487974
41 + 487933 = 487974
83 + 487891 = 487974
101 + 487873 = 487974
131 + 487843 = 487974
163 + 487811 = 487974
181 + 487793 = 487974
191 + 487783 = 487974

Showing the first eight; more decompositions exist.
