Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512900, here are decompositions:

19 + 33512881 = 33512900
61 + 33512839 = 33512900
229 + 33512671 = 33512900
271 + 33512629 = 33512900
283 + 33512617 = 33512900
331 + 33512569 = 33512900
367 + 33512533 = 33512900
397 + 33512503 = 33512900

Showing the first eight; more decompositions exist.
