Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67870, here are decompositions:

3 + 67867 = 67870
17 + 67853 = 67870
41 + 67829 = 67870
107 + 67763 = 67870
113 + 67757 = 67870
137 + 67733 = 67870
191 + 67679 = 67870
239 + 67631 = 67870

Showing the first eight; more decompositions exist.
