Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978340, here are decompositions:

3 + 978337 = 978340
17 + 978323 = 978340
53 + 978287 = 978340
71 + 978269 = 978340
101 + 978239 = 978340
107 + 978233 = 978340
131 + 978209 = 978340
137 + 978203 = 978340

Showing the first eight; more decompositions exist.
