Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69810, here are decompositions:

31 + 69779 = 69810
43 + 69767 = 69810
47 + 69763 = 69810
71 + 69739 = 69810
73 + 69737 = 69810
101 + 69709 = 69810
113 + 69697 = 69810
149 + 69661 = 69810

Showing the first eight; more decompositions exist.
