Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978388, here are decompositions:

29 + 978359 = 978388
41 + 978347 = 978388
101 + 978287 = 978388
149 + 978239 = 978388
179 + 978209 = 978388
239 + 978149 = 978388
311 + 978077 = 978388
317 + 978071 = 978388

Showing the first eight; more decompositions exist.
