Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985072, here are decompositions:

59 + 985013 = 985072
113 + 984959 = 985072
149 + 984923 = 985072
191 + 984881 = 985072
311 + 984761 = 985072
383 + 984689 = 985072
461 + 984611 = 985072
479 + 984593 = 985072

Showing the first eight; more decompositions exist.
