Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942642, here are decompositions:

5 + 942637 = 942642
59 + 942583 = 942642
73 + 942569 = 942642
101 + 942541 = 942642
163 + 942479 = 942642
193 + 942449 = 942642
241 + 942401 = 942642
271 + 942371 = 942642

Showing the first eight; more decompositions exist.
