Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521918, here are decompositions:

97 + 33521821 = 33521918
229 + 33521689 = 33521918
271 + 33521647 = 33521918
379 + 33521539 = 33521918
457 + 33521461 = 33521918
487 + 33521431 = 33521918
739 + 33521179 = 33521918
1117 + 33520801 = 33521918

Showing the first eight; more decompositions exist.
