Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042870, here are decompositions:

41 + 1042829 = 1042870
71 + 1042799 = 1042870
89 + 1042781 = 1042870
137 + 1042733 = 1042870
167 + 1042703 = 1042870
239 + 1042631 = 1042870
251 + 1042619 = 1042870
263 + 1042607 = 1042870

Showing the first eight; more decompositions exist.
