Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978378, here are decompositions:

19 + 978359 = 978378
29 + 978349 = 978378
31 + 978347 = 978378
41 + 978337 = 978378
101 + 978277 = 978378
109 + 978269 = 978378
139 + 978239 = 978378
197 + 978181 = 978378

Showing the first eight; more decompositions exist.
