Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487572, here are decompositions:

11 + 33487561 = 33487572
29 + 33487543 = 33487572
59 + 33487513 = 33487572
61 + 33487511 = 33487572
149 + 33487423 = 33487572
179 + 33487393 = 33487572
229 + 33487343 = 33487572
263 + 33487309 = 33487572

Showing the first eight; more decompositions exist.
