Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945320, here are decompositions:

31 + 945289 = 945320
109 + 945211 = 945320
283 + 945037 = 945320
367 + 944953 = 945320
421 + 944899 = 945320
433 + 944887 = 945320
463 + 944857 = 945320
487 + 944833 = 945320

Showing the first eight; more decompositions exist.
