Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982642, here are decompositions:

29 + 982613 = 982642
53 + 982589 = 982642
71 + 982571 = 982642
83 + 982559 = 982642
149 + 982493 = 982642
239 + 982403 = 982642
431 + 982211 = 982642
491 + 982151 = 982642

Showing the first eight; more decompositions exist.
