Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487940, here are decompositions:

37 + 33487903 = 33487940
127 + 33487813 = 33487940
181 + 33487759 = 33487940
223 + 33487717 = 33487940
349 + 33487591 = 33487940
379 + 33487561 = 33487940
397 + 33487543 = 33487940
433 + 33487507 = 33487940

Showing the first eight; more decompositions exist.
