Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33541642, here are decompositions:

23 + 33541619 = 33541642
41 + 33541601 = 33541642
179 + 33541463 = 33541642
311 + 33541331 = 33541642
383 + 33541259 = 33541642
509 + 33541133 = 33541642
569 + 33541073 = 33541642
599 + 33541043 = 33541642

Showing the first eight; more decompositions exist.
