Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543142, here are decompositions:

71 + 33543071 = 33543142
179 + 33542963 = 33543142
239 + 33542903 = 33543142
359 + 33542783 = 33543142
383 + 33542759 = 33543142
389 + 33542753 = 33543142
419 + 33542723 = 33543142
431 + 33542711 = 33543142

Showing the first eight; more decompositions exist.
