Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561072, here are decompositions:

5 + 33561067 = 33561072
19 + 33561053 = 33561072
53 + 33561019 = 33561072
59 + 33561013 = 33561072
73 + 33560999 = 33561072
89 + 33560983 = 33561072
191 + 33560881 = 33561072
229 + 33560843 = 33561072

Showing the first eight; more decompositions exist.
