Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039942, here are decompositions:

11 + 1039931 = 1039942
41 + 1039901 = 1039942
173 + 1039769 = 1039942
179 + 1039763 = 1039942
311 + 1039631 = 1039942
389 + 1039553 = 1039942
461 + 1039481 = 1039942
479 + 1039463 = 1039942

Showing the first eight; more decompositions exist.
