Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70878, here are decompositions:

11 + 70867 = 70878
29 + 70849 = 70878
37 + 70841 = 70878
109 + 70769 = 70878
149 + 70729 = 70878
191 + 70687 = 70878
211 + 70667 = 70878
239 + 70639 = 70878

Showing the first eight; more decompositions exist.
