Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10642, here are decompositions:

3 + 10639 = 10642
11 + 10631 = 10642
29 + 10613 = 10642
41 + 10601 = 10642
53 + 10589 = 10642
83 + 10559 = 10642
113 + 10529 = 10642
179 + 10463 = 10642

Showing the first eight; more decompositions exist.
