Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978398, here are decompositions:

61 + 978337 = 978398
181 + 978217 = 978398
241 + 978157 = 978398
307 + 978091 = 978398
331 + 978067 = 978398
349 + 978049 = 978398
367 + 978031 = 978398
397 + 978001 = 978398

Showing the first eight; more decompositions exist.
