Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477890, here are decompositions:

43 + 477847 = 477890
67 + 477823 = 477890
79 + 477811 = 477890
151 + 477739 = 477890
163 + 477727 = 477890
271 + 477619 = 477890
313 + 477577 = 477890
337 + 477553 = 477890

Showing the first eight; more decompositions exist.
