Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521642, here are decompositions:

13 + 33521629 = 33521642
19 + 33521623 = 33521642
103 + 33521539 = 33521642
181 + 33521461 = 33521642
211 + 33521431 = 33521642
241 + 33521401 = 33521642
421 + 33521221 = 33521642
463 + 33521179 = 33521642

Showing the first eight; more decompositions exist.
