Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980280, here are decompositions:

19 + 980261 = 980280
31 + 980249 = 980280
61 + 980219 = 980280
83 + 980197 = 980280
101 + 980179 = 980280
107 + 980173 = 980280
131 + 980149 = 980280
149 + 980131 = 980280

Showing the first eight; more decompositions exist.
