Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945278, here are decompositions:

67 + 945211 = 945278
127 + 945151 = 945278
241 + 945037 = 945278
349 + 944929 = 945278
379 + 944899 = 945278
421 + 944857 = 945278
457 + 944821 = 945278
547 + 944731 = 945278

Showing the first eight; more decompositions exist.
