Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003942, here are decompositions:

11 + 1003931 = 1003942
29 + 1003913 = 1003942
53 + 1003889 = 1003942
101 + 1003841 = 1003942
179 + 1003763 = 1003942
263 + 1003679 = 1003942
311 + 1003631 = 1003942
353 + 1003589 = 1003942

Showing the first eight; more decompositions exist.
