Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978370, here are decompositions:

11 + 978359 = 978370
23 + 978347 = 978370
47 + 978323 = 978370
83 + 978287 = 978370
101 + 978269 = 978370
131 + 978239 = 978370
137 + 978233 = 978370
167 + 978203 = 978370

Showing the first eight; more decompositions exist.
