Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491680, here are decompositions:

41 + 33491639 = 33491680
59 + 33491621 = 33491680
113 + 33491567 = 33491680
137 + 33491543 = 33491680
191 + 33491489 = 33491680
239 + 33491441 = 33491680
263 + 33491417 = 33491680
293 + 33491387 = 33491680

Showing the first eight; more decompositions exist.
