Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571642, here are decompositions:

3 + 33571639 = 33571642
23 + 33571619 = 33571642
179 + 33571463 = 33571642
191 + 33571451 = 33571642
389 + 33571253 = 33571642
431 + 33571211 = 33571642
479 + 33571163 = 33571642
491 + 33571151 = 33571642

Showing the first eight; more decompositions exist.
