Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 983690, here are decompositions:

31 + 983659 = 983690
73 + 983617 = 983690
109 + 983581 = 983690
157 + 983533 = 983690
163 + 983527 = 983690
199 + 983491 = 983690
229 + 983461 = 983690
241 + 983449 = 983690

Showing the first eight; more decompositions exist.
