Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985388, here are decompositions:

37 + 985351 = 985388
97 + 985291 = 985388
109 + 985279 = 985388
211 + 985177 = 985388
331 + 985057 = 985388
457 + 984931 = 985388
541 + 984847 = 985388
571 + 984817 = 985388

Showing the first eight; more decompositions exist.
