Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985172, here are decompositions:

43 + 985129 = 985172
109 + 985063 = 985172
241 + 984931 = 985172
313 + 984859 = 985172
439 + 984733 = 985172
631 + 984541 = 985172
691 + 984481 = 985172
751 + 984421 = 985172

Showing the first eight; more decompositions exist.
