Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942988, here are decompositions:

5 + 942983 = 942988
71 + 942917 = 942988
89 + 942899 = 942988
131 + 942857 = 942988
239 + 942749 = 942988
269 + 942719 = 942988
419 + 942569 = 942988
461 + 942527 = 942988

Showing the first eight; more decompositions exist.
