Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978402, here are decompositions:

13 + 978389 = 978402
43 + 978359 = 978402
53 + 978349 = 978402
59 + 978343 = 978402
79 + 978323 = 978402
163 + 978239 = 978402
179 + 978223 = 978402
193 + 978209 = 978402

Showing the first eight; more decompositions exist.
