Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978380, here are decompositions:

31 + 978349 = 978380
37 + 978343 = 978380
43 + 978337 = 978380
97 + 978283 = 978380
103 + 978277 = 978380
157 + 978223 = 978380
163 + 978217 = 978380
199 + 978181 = 978380

Showing the first eight; more decompositions exist.
