Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982180, here are decompositions:

29 + 982151 = 982180
47 + 982133 = 982180
83 + 982097 = 982180
113 + 982067 = 982180
197 + 981983 = 982180
233 + 981947 = 982180
239 + 981941 = 982180
293 + 981887 = 982180

Showing the first eight; more decompositions exist.
