Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561140, here are decompositions:

37 + 33561103 = 33561140
61 + 33561079 = 33561140
73 + 33561067 = 33561140
127 + 33561013 = 33561140
157 + 33560983 = 33561140
211 + 33560929 = 33561140
271 + 33560869 = 33561140
307 + 33560833 = 33561140

Showing the first eight; more decompositions exist.
