Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69890, here are decompositions:

13 + 69877 = 69890
31 + 69859 = 69890
43 + 69847 = 69890
61 + 69829 = 69890
127 + 69763 = 69890
151 + 69739 = 69890
181 + 69709 = 69890
193 + 69697 = 69890

Showing the first eight; more decompositions exist.
