Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84720, here are decompositions:

7 + 84713 = 84720
19 + 84701 = 84720
23 + 84697 = 84720
29 + 84691 = 84720
47 + 84673 = 84720
61 + 84659 = 84720
67 + 84653 = 84720
71 + 84649 = 84720

Showing the first eight; more decompositions exist.
