Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152978, here are decompositions:

19 + 152959 = 152978
31 + 152947 = 152978
37 + 152941 = 152978
79 + 152899 = 152978
127 + 152851 = 152978
139 + 152839 = 152978
157 + 152821 = 152978
211 + 152767 = 152978

Showing the first eight; more decompositions exist.
