Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042894, here are decompositions:

113 + 1042781 = 1042894
191 + 1042703 = 1042894
263 + 1042631 = 1042894
311 + 1042583 = 1042894
317 + 1042577 = 1042894
443 + 1042451 = 1042894
467 + 1042427 = 1042894
521 + 1042373 = 1042894

Showing the first eight; more decompositions exist.
