Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945398, here are decompositions:

7 + 945391 = 945398
31 + 945367 = 945398
67 + 945331 = 945398
109 + 945289 = 945398
367 + 945031 = 945398
499 + 944899 = 945398
541 + 944857 = 945398
577 + 944821 = 945398

Showing the first eight; more decompositions exist.
