Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490900, here are decompositions:

11 + 33490889 = 33490900
59 + 33490841 = 33490900
83 + 33490817 = 33490900
137 + 33490763 = 33490900
263 + 33490637 = 33490900
293 + 33490607 = 33490900
353 + 33490547 = 33490900
491 + 33490409 = 33490900

Showing the first eight; more decompositions exist.
