Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942542, here are decompositions:

103 + 942439 = 942542
109 + 942433 = 942542
229 + 942313 = 942542
241 + 942301 = 942542
373 + 942169 = 942542
379 + 942163 = 942542
463 + 942079 = 942542
499 + 942043 = 942542

Showing the first eight; more decompositions exist.
