Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553640, here are decompositions:

7 + 33553633 = 33553640
103 + 33553537 = 33553640
151 + 33553489 = 33553640
223 + 33553417 = 33553640
271 + 33553369 = 33553640
277 + 33553363 = 33553640
283 + 33553357 = 33553640
313 + 33553327 = 33553640

Showing the first eight; more decompositions exist.
