Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487804, here are decompositions:

11 + 487793 = 487804
47 + 487757 = 487804
71 + 487733 = 487804
101 + 487703 = 487804
113 + 487691 = 487804
167 + 487637 = 487804
197 + 487607 = 487804
347 + 487457 = 487804

Showing the first eight; more decompositions exist.
