Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 984642, here are decompositions:

31 + 984611 = 984642
59 + 984583 = 984642
79 + 984563 = 984642
101 + 984541 = 984642
103 + 984539 = 984642
151 + 984491 = 984642
181 + 984461 = 984642
229 + 984413 = 984642

Showing the first eight; more decompositions exist.
