Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561180, here are decompositions:

7 + 33561173 = 33561180
11 + 33561169 = 33561180
19 + 33561161 = 33561180
41 + 33561139 = 33561180
101 + 33561079 = 33561180
113 + 33561067 = 33561180
127 + 33561053 = 33561180
157 + 33561023 = 33561180

Showing the first eight; more decompositions exist.
