Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542638, here are decompositions:

71 + 33542567 = 33542638
149 + 33542489 = 33542638
317 + 33542321 = 33542638
401 + 33542237 = 33542638
419 + 33542219 = 33542638
449 + 33542189 = 33542638
491 + 33542147 = 33542638
587 + 33542051 = 33542638

Showing the first eight; more decompositions exist.
