Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487994, here are decompositions:

61 + 487933 = 487994
97 + 487897 = 487994
103 + 487891 = 487994
151 + 487843 = 487994
163 + 487831 = 487994
211 + 487783 = 487994
277 + 487717 = 487994
313 + 487681 = 487994

Showing the first eight; more decompositions exist.
