Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945218, here are decompositions:

7 + 945211 = 945218
67 + 945151 = 945218
181 + 945037 = 945218
331 + 944887 = 945218
397 + 944821 = 945218
487 + 944731 = 945218
541 + 944677 = 945218
691 + 944527 = 945218

Showing the first eight; more decompositions exist.
