Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978266, here are decompositions:

43 + 978223 = 978266
109 + 978157 = 978266
193 + 978073 = 978266
199 + 978067 = 978266
229 + 978037 = 978266
463 + 977803 = 978266
547 + 977719 = 978266
673 + 977593 = 978266

Showing the first eight; more decompositions exist.
