Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507620, here are decompositions:

19 + 33507601 = 33507620
43 + 33507577 = 33507620
79 + 33507541 = 33507620
241 + 33507379 = 33507620
313 + 33507307 = 33507620
373 + 33507247 = 33507620
397 + 33507223 = 33507620
409 + 33507211 = 33507620

Showing the first eight; more decompositions exist.
