Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942880, here are decompositions:

11 + 942869 = 942880
23 + 942857 = 942880
53 + 942827 = 942880
101 + 942779 = 942880
131 + 942749 = 942880
227 + 942653 = 942880
311 + 942569 = 942880
353 + 942527 = 942880

Showing the first eight; more decompositions exist.
