Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979138, here are decompositions:

29 + 979109 = 979138
101 + 979037 = 979138
107 + 979031 = 979138
137 + 979001 = 979138
191 + 978947 = 979138
317 + 978821 = 979138
389 + 978749 = 979138
449 + 978689 = 979138

Showing the first eight; more decompositions exist.
