Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011442, here are decompositions:

11 + 1011431 = 1011442
71 + 1011371 = 1011442
83 + 1011359 = 1011442
251 + 1011191 = 1011442
449 + 1010993 = 1011442
461 + 1010981 = 1011442
599 + 1010843 = 1011442
659 + 1010783 = 1011442

Showing the first eight; more decompositions exist.
