Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33610780, here are decompositions:

3 + 33610777 = 33610780
11 + 33610769 = 33610780
149 + 33610631 = 33610780
227 + 33610553 = 33610780
263 + 33610517 = 33610780
311 + 33610469 = 33610780
383 + 33610397 = 33610780
419 + 33610361 = 33610780

Showing the first eight; more decompositions exist.
