Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33544640, here are decompositions:

43 + 33544597 = 33544640
61 + 33544579 = 33544640
127 + 33544513 = 33544640
139 + 33544501 = 33544640
163 + 33544477 = 33544640
271 + 33544369 = 33544640
373 + 33544267 = 33544640
379 + 33544261 = 33544640

Showing the first eight; more decompositions exist.
