Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508880, here are decompositions:

73 + 33508807 = 33508880
79 + 33508801 = 33508880
127 + 33508753 = 33508880
151 + 33508729 = 33508880
241 + 33508639 = 33508880
331 + 33508549 = 33508880
373 + 33508507 = 33508880
409 + 33508471 = 33508880

Showing the first eight; more decompositions exist.
