Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84820, here are decompositions:

11 + 84809 = 84820
59 + 84761 = 84820
83 + 84737 = 84820
89 + 84731 = 84820
101 + 84719 = 84820
107 + 84713 = 84820
167 + 84653 = 84820
191 + 84629 = 84820

Showing the first eight; more decompositions exist.
