Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942842, here are decompositions:

31 + 942811 = 942842
79 + 942763 = 942842
151 + 942691 = 942842
181 + 942661 = 942842
409 + 942433 = 942842
541 + 942301 = 942842
619 + 942223 = 942842
643 + 942199 = 942842

Showing the first eight; more decompositions exist.
