Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980812, here are decompositions:

11 + 980801 = 980812
83 + 980729 = 980812
101 + 980711 = 980812
191 + 980621 = 980812
233 + 980579 = 980812
263 + 980549 = 980812
353 + 980459 = 980812
389 + 980423 = 980812

Showing the first eight; more decompositions exist.
