Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481868, here are decompositions:

31 + 33481837 = 33481868
37 + 33481831 = 33481868
61 + 33481807 = 33481868
67 + 33481801 = 33481868
109 + 33481759 = 33481868
139 + 33481729 = 33481868
241 + 33481627 = 33481868
271 + 33481597 = 33481868

Showing the first eight; more decompositions exist.
