Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491830, here are decompositions:

3 + 33491827 = 33491830
83 + 33491747 = 33491830
89 + 33491741 = 33491830
101 + 33491729 = 33491830
137 + 33491693 = 33491830
149 + 33491681 = 33491830
191 + 33491639 = 33491830
227 + 33491603 = 33491830

Showing the first eight; more decompositions exist.
