Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491910, here are decompositions:

61 + 33491849 = 33491910
73 + 33491837 = 33491910
79 + 33491831 = 33491910
83 + 33491827 = 33491910
107 + 33491803 = 33491910
131 + 33491779 = 33491910
149 + 33491761 = 33491910
163 + 33491747 = 33491910

Showing the first eight; more decompositions exist.
