Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978436, here are decompositions:

23 + 978413 = 978436
47 + 978389 = 978436
89 + 978347 = 978436
113 + 978323 = 978436
149 + 978287 = 978436
167 + 978269 = 978436
197 + 978239 = 978436
227 + 978209 = 978436

Showing the first eight; more decompositions exist.
