Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 983638, here are decompositions:

41 + 983597 = 983638
59 + 983579 = 983638
107 + 983531 = 983638
191 + 983447 = 983638
197 + 983441 = 983638
311 + 983327 = 983638
449 + 983189 = 983638
569 + 983069 = 983638

Showing the first eight; more decompositions exist.
