Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479890, here are decompositions:

11 + 479879 = 479890
29 + 479861 = 479890
107 + 479783 = 479890
113 + 479777 = 479890
137 + 479753 = 479890
251 + 479639 = 479890
347 + 479543 = 479890
401 + 479489 = 479890

Showing the first eight; more decompositions exist.
