Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518900, here are decompositions:

7 + 33518893 = 33518900
67 + 33518833 = 33518900
223 + 33518677 = 33518900
277 + 33518623 = 33518900
313 + 33518587 = 33518900
409 + 33518491 = 33518900
463 + 33518437 = 33518900
607 + 33518293 = 33518900

Showing the first eight; more decompositions exist.
