Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512572, here are decompositions:

3 + 33512569 = 33512572
101 + 33512471 = 33512572
131 + 33512441 = 33512572
263 + 33512309 = 33512572
293 + 33512279 = 33512572
383 + 33512189 = 33512572
419 + 33512153 = 33512572
461 + 33512111 = 33512572

Showing the first eight; more decompositions exist.
