Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942540, here are decompositions:

13 + 942527 = 942540
19 + 942521 = 942540
31 + 942509 = 942540
61 + 942479 = 942540
101 + 942439 = 942540
103 + 942437 = 942540
107 + 942433 = 942540
139 + 942401 = 942540

Showing the first eight; more decompositions exist.
