Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493902, here are decompositions:

11 + 33493891 = 33493902
31 + 33493871 = 33493902
61 + 33493841 = 33493902
73 + 33493829 = 33493902
89 + 33493813 = 33493902
229 + 33493673 = 33493902
263 + 33493639 = 33493902
283 + 33493619 = 33493902

Showing the first eight; more decompositions exist.
