Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84890, here are decompositions:

19 + 84871 = 84890
31 + 84859 = 84890
79 + 84811 = 84890
97 + 84793 = 84890
103 + 84787 = 84890
139 + 84751 = 84890
193 + 84697 = 84890
199 + 84691 = 84890

Showing the first eight; more decompositions exist.
