Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518920, here are decompositions:

11 + 33518909 = 33518920
47 + 33518873 = 33518920
59 + 33518861 = 33518920
101 + 33518819 = 33518920
107 + 33518813 = 33518920
137 + 33518783 = 33518920
251 + 33518669 = 33518920
269 + 33518651 = 33518920

Showing the first eight; more decompositions exist.
