Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 983978, here are decompositions:

67 + 983911 = 983978
97 + 983881 = 983978
241 + 983737 = 983978
277 + 983701 = 983978
397 + 983581 = 983978
421 + 983557 = 983978
487 + 983491 = 983978
547 + 983431 = 983978

Showing the first eight; more decompositions exist.
