Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042942, here are decompositions:

11 + 1042931 = 1042942
41 + 1042901 = 1042942
113 + 1042829 = 1042942
233 + 1042709 = 1042942
239 + 1042703 = 1042942
311 + 1042631 = 1042942
359 + 1042583 = 1042942
419 + 1042523 = 1042942

Showing the first eight; more decompositions exist.
