Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33574528, here are decompositions:

11 + 33574517 = 33574528
17 + 33574511 = 33574528
41 + 33574487 = 33574528
137 + 33574391 = 33574528
167 + 33574361 = 33574528
269 + 33574259 = 33574528
431 + 33574097 = 33574528
461 + 33574067 = 33574528

Showing the first eight; more decompositions exist.
