Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491530, here are decompositions:

41 + 33491489 = 33491530
71 + 33491459 = 33491530
89 + 33491441 = 33491530
113 + 33491417 = 33491530
167 + 33491363 = 33491530
197 + 33491333 = 33491530
227 + 33491303 = 33491530
263 + 33491267 = 33491530

Showing the first eight; more decompositions exist.
