Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506890, here are decompositions:

3 + 506887 = 506890
17 + 506873 = 506890
29 + 506861 = 506890
47 + 506843 = 506890
53 + 506837 = 506890
107 + 506783 = 506890
191 + 506699 = 506890
227 + 506663 = 506890

Showing the first eight; more decompositions exist.
