Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978940, here are decompositions:

23 + 978917 = 978940
89 + 978851 = 978940
101 + 978839 = 978940
167 + 978773 = 978940
191 + 978749 = 978940
197 + 978743 = 978940
227 + 978713 = 978940
251 + 978689 = 978940

Showing the first eight; more decompositions exist.
