Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947442, here are decompositions:

11 + 947431 = 947442
19 + 947423 = 947442
29 + 947413 = 947442
31 + 947411 = 947442
53 + 947389 = 947442
59 + 947383 = 947442
61 + 947381 = 947442
73 + 947369 = 947442

Showing the first eight; more decompositions exist.
