Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511040, here are decompositions:

67 + 33510973 = 33511040
127 + 33510913 = 33511040
139 + 33510901 = 33511040
163 + 33510877 = 33511040
193 + 33510847 = 33511040
313 + 33510727 = 33511040
349 + 33510691 = 33511040
457 + 33510583 = 33511040

Showing the first eight; more decompositions exist.
