Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84210, here are decompositions:

11 + 84199 = 84210
19 + 84191 = 84210
29 + 84181 = 84210
31 + 84179 = 84210
47 + 84163 = 84210
67 + 84143 = 84210
73 + 84137 = 84210
79 + 84131 = 84210

Showing the first eight; more decompositions exist.
