Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 983938, here are decompositions:

89 + 983849 = 983938
149 + 983789 = 983938
167 + 983771 = 983938
239 + 983699 = 983938
359 + 983579 = 983938
419 + 983519 = 983938
491 + 983447 = 983938
509 + 983429 = 983938

Showing the first eight; more decompositions exist.
