Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985978, here are decompositions:

5 + 985973 = 985978
41 + 985937 = 985978
101 + 985877 = 985978
107 + 985871 = 985978
179 + 985799 = 985978
197 + 985781 = 985978
269 + 985709 = 985978
311 + 985667 = 985978

Showing the first eight; more decompositions exist.
