Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33499640, here are decompositions:

3 + 33499637 = 33499640
7 + 33499633 = 33499640
19 + 33499621 = 33499640
67 + 33499573 = 33499640
157 + 33499483 = 33499640
193 + 33499447 = 33499640
313 + 33499327 = 33499640
373 + 33499267 = 33499640

Showing the first eight; more decompositions exist.
