Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942538, here are decompositions:

11 + 942527 = 942538
17 + 942521 = 942538
29 + 942509 = 942538
59 + 942479 = 942538
89 + 942449 = 942538
101 + 942437 = 942538
137 + 942401 = 942538
167 + 942371 = 942538

Showing the first eight; more decompositions exist.
