Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1057942, here are decompositions:

23 + 1057919 = 1057942
59 + 1057883 = 1057942
89 + 1057853 = 1057942
239 + 1057703 = 1057942
311 + 1057631 = 1057942
401 + 1057541 = 1057942
449 + 1057493 = 1057942
521 + 1057421 = 1057942

Showing the first eight; more decompositions exist.
