Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980806, here are decompositions:

3 + 980803 = 980806
5 + 980801 = 980806
89 + 980717 = 980806
227 + 980579 = 980806
257 + 980549 = 980806
317 + 980489 = 980806
347 + 980459 = 980806
383 + 980423 = 980806

Showing the first eight; more decompositions exist.
