Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978382, here are decompositions:

23 + 978359 = 978382
59 + 978323 = 978382
113 + 978269 = 978382
149 + 978233 = 978382
173 + 978209 = 978382
179 + 978203 = 978382
233 + 978149 = 978382
269 + 978113 = 978382

Showing the first eight; more decompositions exist.
