Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980872, here are decompositions:

41 + 980831 = 980872
71 + 980801 = 980872
251 + 980621 = 980872
281 + 980591 = 980872
293 + 980579 = 980872
383 + 980489 = 980872
401 + 980471 = 980872
449 + 980423 = 980872

Showing the first eight; more decompositions exist.
