Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978300, here are decompositions:

13 + 978287 = 978300
17 + 978283 = 978300
23 + 978277 = 978300
31 + 978269 = 978300
61 + 978239 = 978300
67 + 978233 = 978300
83 + 978217 = 978300
97 + 978203 = 978300

Showing the first eight; more decompositions exist.
