Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67978, here are decompositions:

11 + 67967 = 67978
17 + 67961 = 67978
47 + 67931 = 67978
149 + 67829 = 67978
227 + 67751 = 67978
269 + 67709 = 67978
347 + 67631 = 67978
359 + 67619 = 67978

Showing the first eight; more decompositions exist.
