Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980840, here are decompositions:

13 + 980827 = 980840
37 + 980803 = 980840
67 + 980773 = 980840
109 + 980731 = 980840
151 + 980689 = 980840
163 + 980677 = 980840
199 + 980641 = 980840
241 + 980599 = 980840

Showing the first eight; more decompositions exist.
