Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980818, here are decompositions:

17 + 980801 = 980818
89 + 980729 = 980818
101 + 980717 = 980818
107 + 980711 = 980818
131 + 980687 = 980818
197 + 980621 = 980818
227 + 980591 = 980818
239 + 980579 = 980818

Showing the first eight; more decompositions exist.
