Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477986, here are decompositions:

13 + 477973 = 477986
73 + 477913 = 477986
139 + 477847 = 477986
163 + 477823 = 477986
349 + 477637 = 477986
367 + 477619 = 477986
409 + 477577 = 477986
433 + 477553 = 477986

Showing the first eight; more decompositions exist.
