Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543442, here are decompositions:

3 + 33543439 = 33543442
83 + 33543359 = 33543442
269 + 33543173 = 33543442
281 + 33543161 = 33543442
293 + 33543149 = 33543442
461 + 33542981 = 33543442
479 + 33542963 = 33543442
503 + 33542939 = 33543442

Showing the first eight; more decompositions exist.
