Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478970, here are decompositions:

3 + 478967 = 478970
7 + 478963 = 478970
43 + 478927 = 478970
73 + 478897 = 478970
109 + 478861 = 478970
127 + 478843 = 478970
139 + 478831 = 478970
157 + 478813 = 478970

Showing the first eight; more decompositions exist.
