Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027942, here are decompositions:

11 + 1027931 = 1027942
59 + 1027883 = 1027942
89 + 1027853 = 1027942
101 + 1027841 = 1027942
191 + 1027751 = 1027942
239 + 1027703 = 1027942
263 + 1027679 = 1027942
449 + 1027493 = 1027942

Showing the first eight; more decompositions exist.
