Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 983438, here are decompositions:

7 + 983431 = 983438
31 + 983407 = 983438
61 + 983377 = 983438
67 + 983371 = 983438
109 + 983329 = 983438
139 + 983299 = 983438
199 + 983239 = 983438
229 + 983209 = 983438

Showing the first eight; more decompositions exist.
