Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84660, here are decompositions:

7 + 84653 = 84660
11 + 84649 = 84660
29 + 84631 = 84660
31 + 84629 = 84660
71 + 84589 = 84660
101 + 84559 = 84660
109 + 84551 = 84660
127 + 84533 = 84660

Showing the first eight; more decompositions exist.
