Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491856, here are decompositions:

7 + 33491849 = 33491856
19 + 33491837 = 33491856
23 + 33491833 = 33491856
29 + 33491827 = 33491856
53 + 33491803 = 33491856
89 + 33491767 = 33491856
109 + 33491747 = 33491856
127 + 33491729 = 33491856

Showing the first eight; more decompositions exist.
