Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33591572, here are decompositions:

19 + 33591553 = 33591572
73 + 33591499 = 33591572
103 + 33591469 = 33591572
109 + 33591463 = 33591572
163 + 33591409 = 33591572
229 + 33591343 = 33591572
283 + 33591289 = 33591572
349 + 33591223 = 33591572

Showing the first eight; more decompositions exist.
