Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553880, here are decompositions:

43 + 33553837 = 33553880
109 + 33553771 = 33553880
223 + 33553657 = 33553880
229 + 33553651 = 33553880
331 + 33553549 = 33553880
463 + 33553417 = 33553880
523 + 33553357 = 33553880
709 + 33553171 = 33553880

Showing the first eight; more decompositions exist.
