Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530900, here are decompositions:

43 + 33530857 = 33530900
127 + 33530773 = 33530900
199 + 33530701 = 33530900
223 + 33530677 = 33530900
283 + 33530617 = 33530900
307 + 33530593 = 33530900
331 + 33530569 = 33530900
349 + 33530551 = 33530900

Showing the first eight; more decompositions exist.
