Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487922, here are decompositions:

31 + 487891 = 487922
79 + 487843 = 487922
103 + 487819 = 487922
139 + 487783 = 487922
181 + 487741 = 487922
241 + 487681 = 487922
271 + 487651 = 487922
433 + 487489 = 487922

Showing the first eight; more decompositions exist.
