Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979172, here are decompositions:

13 + 979159 = 979172
79 + 979093 = 979172
109 + 979063 = 979172
163 + 979009 = 979172
199 + 978973 = 979172
241 + 978931 = 979172
373 + 978799 = 979172
631 + 978541 = 979172

Showing the first eight; more decompositions exist.
