Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978548, here are decompositions:

7 + 978541 = 978548
37 + 978511 = 978548
199 + 978349 = 978548
211 + 978337 = 978548
271 + 978277 = 978548
331 + 978217 = 978548
367 + 978181 = 978548
397 + 978151 = 978548

Showing the first eight; more decompositions exist.
