Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68990, here are decompositions:

43 + 68947 = 68990
73 + 68917 = 68990
109 + 68881 = 68990
127 + 68863 = 68990
199 + 68791 = 68990
223 + 68767 = 68990
241 + 68749 = 68990
277 + 68713 = 68990

Showing the first eight; more decompositions exist.
