Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980864, here are decompositions:

13 + 980851 = 980864
37 + 980827 = 980864
61 + 980803 = 980864
223 + 980641 = 980864
271 + 980593 = 980864
277 + 980587 = 980864
307 + 980557 = 980864
373 + 980491 = 980864

Showing the first eight; more decompositions exist.
