Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 983278, here are decompositions:

11 + 983267 = 983278
17 + 983261 = 983278
89 + 983189 = 983278
137 + 983141 = 983278
311 + 982967 = 983278
347 + 982931 = 983278
431 + 982847 = 983278
449 + 982829 = 983278

Showing the first eight; more decompositions exist.
