Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978278, here are decompositions:

61 + 978217 = 978278
97 + 978181 = 978278
127 + 978151 = 978278
199 + 978079 = 978278
211 + 978067 = 978278
229 + 978049 = 978278
241 + 978037 = 978278
271 + 978007 = 978278

Showing the first eight; more decompositions exist.
