Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471642, here are decompositions:

13 + 33471629 = 33471642
59 + 33471583 = 33471642
89 + 33471553 = 33471642
101 + 33471541 = 33471642
109 + 33471533 = 33471642
131 + 33471511 = 33471642
151 + 33471491 = 33471642
163 + 33471479 = 33471642

Showing the first eight; more decompositions exist.
