Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581740, here are decompositions:

47 + 33581693 = 33581740
53 + 33581687 = 33581740
167 + 33581573 = 33581740
347 + 33581393 = 33581740
359 + 33581381 = 33581740
389 + 33581351 = 33581740
419 + 33581321 = 33581740
443 + 33581297 = 33581740

Showing the first eight; more decompositions exist.
