Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971920, here are decompositions:

3 + 971917 = 971920
17 + 971903 = 971920
137 + 971783 = 971920
167 + 971753 = 971920
197 + 971723 = 971920
227 + 971693 = 971920
269 + 971651 = 971920
281 + 971639 = 971920

Showing the first eight; more decompositions exist.
