Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980866, here are decompositions:

137 + 980729 = 980866
149 + 980717 = 980866
179 + 980687 = 980866
317 + 980549 = 980866
443 + 980423 = 980866
449 + 980417 = 980866
503 + 980363 = 980866
617 + 980249 = 980866

Showing the first eight; more decompositions exist.
