Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491874, here are decompositions:

37 + 33491837 = 33491874
41 + 33491833 = 33491874
43 + 33491831 = 33491874
47 + 33491827 = 33491874
71 + 33491803 = 33491874
107 + 33491767 = 33491874
113 + 33491761 = 33491874
127 + 33491747 = 33491874

Showing the first eight; more decompositions exist.
