Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84872, here are decompositions:

3 + 84869 = 84872
13 + 84859 = 84872
61 + 84811 = 84872
79 + 84793 = 84872
181 + 84691 = 84872
199 + 84673 = 84872
223 + 84649 = 84872
241 + 84631 = 84872

Showing the first eight; more decompositions exist.
