Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479840, here are decompositions:

7 + 479833 = 479840
19 + 479821 = 479840
43 + 479797 = 479840
79 + 479761 = 479840
139 + 479701 = 479840
211 + 479629 = 479840
241 + 479599 = 479840
271 + 479569 = 479840

Showing the first eight; more decompositions exist.
