Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980180, here are decompositions:

7 + 980173 = 980180
31 + 980149 = 980180
43 + 980137 = 980180
73 + 980107 = 980180
109 + 980071 = 980180
193 + 979987 = 980180
211 + 979969 = 980180
307 + 979873 = 980180

Showing the first eight; more decompositions exist.
