Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478930, here are decompositions:

3 + 478927 = 478930
17 + 478913 = 478930
29 + 478901 = 478930
59 + 478871 = 478930
107 + 478823 = 478930
167 + 478763 = 478930
191 + 478739 = 478930
233 + 478697 = 478930

Showing the first eight; more decompositions exist.
