Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542842, here are decompositions:

41 + 33542801 = 33542842
59 + 33542783 = 33542842
83 + 33542759 = 33542842
89 + 33542753 = 33542842
131 + 33542711 = 33542842
239 + 33542603 = 33542842
269 + 33542573 = 33542842
353 + 33542489 = 33542842

Showing the first eight; more decompositions exist.
