Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002978, here are decompositions:

5 + 1002973 = 1002978
47 + 1002931 = 1002978
61 + 1002917 = 1002978
79 + 1002899 = 1002978
107 + 1002871 = 1002978
127 + 1002851 = 1002978
157 + 1002821 = 1002978
181 + 1002797 = 1002978

Showing the first eight; more decompositions exist.
